Pulley and wheel and axle

Explain how the wheel and axle is a force multiplier

A car weighs 1800 kg . The distance between its front and back axles is 1.8 m . Its centre of gravity is 1.05 m behind the front axle. Determine the force exerted by the level ground on each front wheel and each back wheel.

All the surface and pulleys are frictionless in the shown arrangement. Pulleys P and Q are massless .The force applied by clamp on pulley P is

Acceleration of pulleys and blocks are as shown in the figure. All pulleys & strings are massless & frictionless magnitude of a_(A) and a_(B) are : .

Name the type of a single pulley that has an ideal mechanical advantage equal to 2. draw a labelled diagram of the pulley mentioned by you.

The pulley A and C are fixed while the pulley B is movable. A mass M_2 is attached to pulley B , while the string has masses M_1 and M_3 at the two ends. Find the acceleration of each mass .

In the pulley system shown in figure the movable pulleys A,B and C are of mass 1 kg each D and E are fixed pulleys are light and inexensible. Choose the correct alternative (s).

A screw driver and a door knob are examples of a .................. (screw/wheel and axle).

The mechanical advantage of a wheel axle is 5 what will be thereforce required to lift a 200kg wt?
