Why are speed ratio and mechanical advantage never the same?
Speed ratio and mechanical advantage are not the same because they are inversely related. Speed ratio is a measure of how much the input speed is amplified or reduced by a machine, while mechanical advantage is a measure of how much the input force is amplified or reduced. A machine that increases speed will have a mechanical advantage less than one, while a machine that increases force will have a mechanical advantage greater than one.
What is the speed advantage of first class lever?
The speed advantage of a first-class lever is that the distance the force is applied over can be greater than the distance the load moves, allowing for a faster speed at the expense of force. This lever configuration is often used in situations where speed is more important than force, such as in certain types of machinery or tools.
Does gear train provide a force advantage or speed advantage and explain?
Gear Train Advantage Arnel Dela Cruz Does gear train provide a force advantage or speed advantage and explain? Make it shortly A gear train can provide a force advantage or a speed advantage, depending on the arrangement of the gears. When the input gear has a smaller radius than the output gear, the gear train provides a force advantage, as the output gear will rotate more slowly but with greater torque. This is known as a gear reduction. Conversely, when the input gear has a larger radius than the output gear, the gear train provides a speed advantage, as the output gear will rotate more quickly but with less torque. This is known as a gear increase or gear multiplier.
How mechanical advantage is expressed?
Mechanical advantage is expressed as the ratio of the output force to the input force in a mechanical system. It can be calculated by dividing the output force by the input force. A mechanical advantage greater than 1 indicates that the machine amplifies force, while a mechanical advantage less than 1 indicates a reduction in force but a gain in distance or speed.
What is a specific use of a pulley with a mechanical advantage of 1?
A pulley with a mechanical advantage of 1 is used to change the direction of a force without providing any advantage in strength or speed. It allows the force to be redirected, such as in a flagpole system where the force is redirected downward for ease of operation.
What is the difference between real mechanical advantage and speed ratio?
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
Which statement is true about the ideal mechanical advantage of a third-class lever?
mechanical advantage is the output force divided by the input force
How do you obtain a force advantage and speed advantage using different gear ratios?
To obtain a force advantage using different gear ratios, you can use a lower gear ratio, which increases torque and allows for greater force output at the wheels, making it easier to start moving or climb steep inclines. Conversely, a higher gear ratio allows for a speed advantage by enabling the vehicle to cover more distance with each engine revolution, making it suitable for faster driving on flat terrain. By strategically selecting gear ratios, you can optimize for either force or speed depending on the driving conditions and requirements.
What gear combination produces the greatest ideal mechanical advantage in the ten-speed bike?
The gear combination that produces the greatest ideal mechanical advantage in a ten-speed bike is usually the largest chainring in the front and the smallest cog in the rear. This combination allows for maximum power output with the least effort exerted by the rider.
Is it true that at 20mph the force of your car impacting surface is 4 times as great at 10mph?
No, the force of impact is not directly proportional to the speed of the car. In a collision, the force of impact is determined by the change in momentum, which is a combination of speed and mass. Doubling the speed does not necessarily mean quadrupling the force of impact.
How do athletic trainers use geometry?
To figure speed, force, momentum, etc. Ie, rate x time = distance, force = mass x acceleration, etc.
What is the difference between a force multiplier and a speed multiplier?
A force multiplier increases the effort force and the mechanical advantage is larger than one (Which means it is easier to move a large load with a small effort). While the speed multiplier does not make the effort easier but makes the load move through a larger distance than the effort. The mechanical advantage of a speed multiplier is usually lower than 1.
