Why is bone anisotropic?
Bone is considered anisotropic because it responds differently if forces are applied in different directions. Bone can handle large forces applied in the longitudinal plane (tension and compression); bone is not as strong in handling forces applied transversely across its surface.The differences between the properties of the cancellous and cortical bone contribute to the anisotropy of the bone. Cancellous bone provides bending strength, and cortical bone provides significant compressive strength.
Write a example for like parallel forces?
the bag of apples ........ the weights of the apples are acting in same direction so it is an example of parallel forces
Does Each consecutive bone lamella has collagen fibers that wrap in alternating directions?
Yes, bone lamellae have collagen fibers that wrap in alternating directions. This alternating pattern, known as a crisscross pattern, provides strength and resiliency to the bone, making it able to withstand stress and bending forces in multiple directions.
What is the role of a vector?
Vectors are mathematical objects that represent quantities with both magnitude and direction. They are commonly used in physics to represent forces, velocities, and accelerations. In computer science, vectors are used to store and manipulate arrays of elements efficiently.
3. Some forces act at a distance and thus do not require .?
Some forces act at a distance and thus do not require direct contact between objects. Examples include gravitational and electromagnetic forces. These forces can influence objects without physical contact due to their field-like nature.
How do you calculate forces acting in the same direction or different directions?
To calculate forces acting in the same direction, simply add the magnitudes of the forces together. For forces acting in different directions, you must consider both the magnitudes and directions of the forces, using vector addition or subtraction to find the resultant force.
Are resultant forces acting in different directions equal?
No, resultant forces acting in different directions are not equal. The resultant force is the net force that results from combining all the individual forces acting on an object, taking into account their direction and magnitude.
What happens to forces moving in different direction?
When forces are moving in different directions, they can either cancel each other out if they are of equal magnitude and in opposite directions, resulting in a net force of zero. If the forces are not equal, the object will experience a resultant force in the direction of the larger force. This resultant force will cause the object to accelerate in that direction according to Newton's second law of motion.
How are the size and direction of action-reaction forces are related?
Size: the same. Direction: the forces are in opposite directions.
Adding a force acting in one direction to a force in another direction is the same as adding a?
as adding a ".... in the opposite direction.
What is meant by like and unlike parallel forces?
Like Parallel forces are the forces that are parallel to each other and have same direction. Unlike parallel forces are the forces that are parallel but have directions opposite to each other.
How do forces work in different directions?
You calculate the vector sum of all the forces acting on the object. For example, if one force is in the positive direction, say 8N, and another force is in the opposite direction, say -7N, the net force would be 8N + (-7N) = 1N.
When 2 forces are acting on an object in opposite directions we combine them by?
When two forces are acting on an object in opposite directions, we combine them by finding the difference between the magnitudes of the two forces. The direction of the resulting force will be in the direction of the larger force.
What do you do when forces are in different directions?
When forces are in different directions, you can resolve them into their components along specific axes. This allows you to analyze their effects separately and find the resultant force in the desired direction. Summing up the components along each axis using vector addition and trigonometry can help determine the overall effect of the forces.
Why don't two forces balance each other?
Two forces may not balance each other if they are acting in different directions or have different magnitudes. When forces are not equal and opposite, they result in acceleration or movement of the object in the direction of the greater force.
Do balanced and unbalanced forces have direction?
Yes, both balanced and unbalanced forces have direction. Balanced forces have equal magnitude and opposite directions, resulting in no overall change in an object's motion. Unbalanced forces have unequal magnitudes or directions, causing changes in an object's motion.
How do you combine forces acting in different directions?
To combine forces acting in different directions, you can use vector addition. Break each force into its horizontal and vertical components, then sum the horizontal components together and the vertical components together to find the resultant force in each direction. Finally, combine the horizontal and vertical components to find the magnitude and direction of the resultant force.
