Describe an inclined plane and obtain an expression for its mechanical advantage.

Define mechanical advantage.

Discuss rolling without slipping of a cylinder down a rough inclined plane and obtain an expression for the coefffcient of friction necessary for the same.

What is the expression for mechanical advantage of a hydraulic press ?

Define mechanical advantage of a lever.

A man uses a rough inclined plane of length 3 m to raise a load of 100 kgwt. If he does 2400 J of work and the inclined plane offers 300 N resistance, find the mechanical advantage (Take g=10 m s^(-2) ).

If the angle of inclination of an inclined plane of 30^(@) , its mechanical advantage is ______

Answer true or false: If a plane is inclined at a steeper angle, its mechanical advantage increases.
