Suppose you use a teaspoon to open a lid. The resistance arm is 1 cm long and the effort arm is 10 cm long.Calculate the mechanical advantage and state what this means in terms of the reduction in the effort force you need.

Suppose a particular lever has a mechanical advantage of 0.5.Determine which two of the following statements about the lever are true. It is a speed multiplierIt is a force multiplierIts effort arm is twice as long as its resistance armIts resistance arm is twice as long as its effort armI'm not sure

What is the mechanical advantage of a lever defined as?Question 6Select one:a.Effort/loadb.Load/fulcrumc.Fulcrum/effortd.Load/effort

True or False: Mechanical Advantage is the amount by which a machine can multiply an input force.

What is the mechanical advantage of a lever with a load of 100 N and an effort of 50 N?Question 18Select one:a.1b.0.5c.3d.2

The roadies at a music concert have to get a piano weighing 2500 N onto a stage 1.5 m high. They have a 6 m-long ramp.Calculate the ideal mechanical advantage of the ramp.With the piano on a small trolley they have to exert 700 N force to push it up the ramp. Determine the actual mechanical advantage of the ramp.Is the actual mechanical advantage greater than, less than, or the same as the ideal mechanical advantage? Explain why this would be.In a world with no friction, calculate the effort force the roadies would need to apply to get the piano up the ramp.Note: Show your calculations.
