Mechanics
Mechanics is the branch of physics that deals with the interactions of objects and forces in the observable world. Questions asking about projectile motion, conservation of energy, and calculus based mechanics are perfect for this topic, but questions about repairs that a mechanic would do belong in our vehicles categories.

Why master piston is smaller then slave piston?
The master piston is smaller than the slave piston in hydraulic systems to create a mechanical advantage. When the smaller master piston is pushed, it generates higher pressure in the hydraulic fluid, which is then transmitted to the larger slave piston. This difference in size allows a smaller force applied to the master piston to produce a larger force at the slave piston, enabling the system to amplify force effectively. This principle is fundamental in applications like hydraulic brakes and lifts.
Which weighs more bucket of apples or bucket of water?
The answer to this question depends on the density of the two given substances. For the same volume a more dense substance will have more mass and will weigh more. Here, if we take buckets of same volume in both cases then the water bucket will be heavier as water is more dense than apples. Also water occupies the entire volume of the bucket while apples cant use up the entire volume of the bucket as they have fixed shape and spaces remain between them.
If two buckets of different volumes are taken then easiest process would be to actually weigh the buckets to find the heavier one. Here, apples considered are the ones grown on apple plants and eaten. For any other substance cast in of shape of apples it's density has to be considered.
If gear X turns clockwise at a constant speed of 10 RPM How does gear Y turn?
Well, honey, if gear X is turning clockwise at a steady 10 RPM, gear Y will also turn clockwise at the same speed if they are directly connected. Now, if gear Y is connected to gear X in a different way, like with different sized gears or belts, then the speed and direction could vary. But hey, as long as gear X keeps on chugging along at 10 RPM, gear Y will follow suit in some way or another.
What is the combination of all the forces acting on an object called?
The combination of all the forces acting on an object is called the net force. The net force is the vector sum of all the individual forces, taking into account both their magnitudes and directions. It determines the overall acceleration or deceleration of the object according to Newton's second law of motion, F=ma.
State what is meant by collinear force?
Oh honey, collinear force simply means forces that act along the same line. It's like having a group of soldiers marching in a straight line, all pushing or pulling in the same direction. So, if you've got forces lined up like a bunch of obedient little ducklings, congratulations, you've got yourself some collinear forces.
What are non examples of net force?
A net force is the vector sum of ALL forces acting on a given object. A "non-example" would include an individual force, when there are other forces involved. For example, if you have a book on a table, the downward force of gravity is NOT the net force, since there are other forces involved.
How do you combine unequal forces acting in opposite directions?
Well, honey, when you've got unequal forces pulling in opposite directions, you need to calculate the net force by subtracting the smaller force from the larger force. The resulting force will determine the overall direction of the object's movement. So, just do the math and watch those forces duke it out!
How do you find the reaction at a pivot when a plank is in equilibrium?
To find the reaction at a pivot when a plank is in equilibrium, you need to consider the forces acting on the plank. The sum of the clockwise moments about the pivot point must be equal to the sum of the anticlockwise moments. This equilibrium condition allows you to calculate the reaction at the pivot using the principle of moments. The reaction at the pivot will be equal in magnitude but opposite in direction to the sum of the other forces acting on the plank.
?
Oh, isn't that a happy little question. When you add a force acting in one direction to a force acting in the opposite direction, it's like creating a delicate balance on your canvas. Just like how we blend colors to create harmony, these forces work together to create equilibrium. Just remember, every stroke you make adds to the beauty of the whole picture.
What is the circumference of a standard magnifying glass?
There is no standard size. Different manufacturers make different sizes, and many make several sizes.
Is a wheelchair a second class lever?
Yes, a wheelchair is considered a second-class lever. In a second-class lever, the load is located between the fulcrum and the effort. In the case of a wheelchair, the fulcrum is the point where the wheel meets the ground, the load is the weight of the person sitting in the wheelchair, and the effort is applied by the person pushing the wheelchair.
Technician A is correct. The UICS, or Uniform Inspection and Communication Standards, do indeed contain standards for automotive repair services. These standards provide guidelines for technicians to follow when inspecting and communicating about vehicle repair needs. On the other hand, automotive maintenance services are typically guided by manufacturer recommendations and service schedules, rather than the UICS.
What is the input and output force of a faucet?

It can be for example in Vector Analysis when you integrate a vector over a certain area the integral arguments (dxdy)together can be a vetor. (actually strictly saing it's a pseudovector)
You want one clamp on one side of the center of the glass and the other clamp on the other side of the center of the glass witrh both equal distance awy from the center.
That is because then both clamps take the same weight ( 1/2 each). I f they are not centered one wil carry a much higher load and also if both are on the same Sid ethe glass will not be centered.
You should put the clamps near the ends as it will easier to have it level over the greatest distance
When did Einstein get married?
* To Mileva Maric on 6 January 1903 (Divorced 14 February 1919). * To Elsa Lowenthal on 2 June 1919.
Einsteins first wife was Mileva Maric, they married in 1903; had two sons (Hans Albert and Eduard) and divorced in 1919.
His second wife was Elsa Lowenthal; they married in 1923 and she died in 1936. They had no children togehter but Einstein adopted Elsa's two daughters (Ilse and Margot) by a previous marriage.
Albert Einstein's second wife, Elsa Lowenthal, was his first cousin on his mother's side. Lowenthal also happened to be his second cousin on his father's side
Mileva and Albert also had a girl before their marrigie in 1902 called Lieserl, but gave her up for adoption as they were not yet married and in those days you had to be married before you could have children.
Mileva met Albert when they were studying together at Polytechnic school in Switzerland. Einsteins parents never wished for Albert to marry Mileva as she was not of the same 'social class' but agreed to their marriage when Alberts father, Hermann was on his death bed.
Elsa and Alberts relationship startes when Albert moved to Berlin. Although he was still married to Mileva their realtionship started nearly the first month he moved in.
Einstein and Mileva Marić married in January 1903. In May 1904. Marić and Einstein divorced on 14 February 1919, having lived apart for five years.
Einstein married Elsa Lowenthal (née Einstein) on 2 June 1919, after having had a relationship with her since 1912. She was his first cousin maternally and his second cousin paternally.
Waves travel in groups due to the phenomenon known as wave grouping or wave packet formation, which occurs when individual waves with similar frequencies and speeds combine. This interaction can amplify certain waves while minimizing others, leading to the distinct grouping effect. Additionally, factors like wind patterns, currents, and the seabed's topography can influence how waves interact, reinforcing the tendency for waves to travel in clusters. Consequently, these groups can create more powerful and organized wave patterns, which are more efficient at transferring energy.
