What is a lever's effort arm?
It is the part of a lever, where external force is applied in order to do work.
What class of lever is your arm?
Arm is the example of 2nd class lever.
What class lever is your arm?
Arm is the example of 2nd class lever.
What is the term for newton meter?
A Newton meter (N·m) is the SI unit for torque, force applied to the lever arm x the length of the lever arm. A Joule, the unit for energy or work, is also a N·m.
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
What is a lever's effort arm?
It is the part of a lever, where external force is applied in order to do work.
What does a Class 1 Lever mean?
A lever in which the force arm is longer than the work-producing arm; thus the work produced is always greater than the energy used, with a resultant high efficiency.
What class of lever is your arm?
Arm is the example of 2nd class lever.
What class lever is your arm?
Arm is the example of 2nd class lever.
What part of LEVER?
the fulcrum, load and effort The three parts of a lever , fulcrum, resistance arm and effort arm, work together to make it possible to lift a weight using less force ...
What is the term for newton meter?
A Newton meter (N·m) is the SI unit for torque, force applied to the lever arm x the length of the lever arm. A Joule, the unit for energy or work, is also a N·m.
If you put a book bag on a resistance arm of a lever what would you need to do to decrease the work input needed to lift the book bag with the lever?
a fulcrum.
Is a lever a machine?
a machine is a tool used to make work easier. any tool that pries something loose is a lever. a lever is a arm that "pivots" (or turns) against a " fulcrum" (or point).
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
Is your arm a lever?
Yes!
What is output arm?
The end of a lever that carries the load is the output arm instead of the input arm which is the end of a lever that force is applied to move the load.
How does the length of effort arm affect the amount of effort needed to lift an object?
The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.
