A simple machine that has a set of two inclined planes that meet at a sharp or pointed edge

A block of weight 1 N rests on a inclined plane of inclination theta with the horizontal. The coefficient of friction between the block and the inclined plane is mu . The minimum force that has to be applied parallel to the inclined plane to make the body just move up the plane is

Ball 1 is released from the top of a smooth inclined plane, the at the same instant ball 2 is projected from the foot of the plance with such a velocity that they meet halfway up the incline. Determine: a.the velocity with which balls are projected and b. the velocity of each ball when they meet. .

At the bottom edge of a smooth wall, an inclined plane is kept at an angle of 45^@ . A uniform ladder of length l and mass M rests on the inclined plane against the wall such that it is perpendicular to the incline. a. If the plane is also smooth, which way will the ladder slide? b. What is the minimum coefficient of friction necessary so that the ladder does not slip on the incline.

There are two inclined planes with the same vertical height, but with different angles of inclination. Two bodies of mass m each are placed at the bottom of the inclined plane. Two external forces of equal magnitude do work in taking the bodies to the top of the inclined plane. Which force does more work?

Two stones A and B are projected from an inclined plane such that A has range up the incline and B has range down the incline. For range of both stones on the incline to be equal in magnitude, pick up the correct condition. ( Neglect air friction 0

The point at which the two coordinate axes meet is called the

A solid cylinder rolls up an inclined plane of angle of inclination 30^(@) . At the bottom of the inclined plane, the centre of mass of the cylinder has a speed of 5 m//s . (a) How far will the cylinder go up the plane ? (B) How long will it take to return to the bottom ?

Particle A is relased form a point P on a smooth inclined plane inclined at an angle alpha with the horizontal. At the same instant another particle B is projected with initial velocity u making an angle beta with the horizontal .Both particle again on inclined plane. What is relation between alpha and beta .

A body is projected up a smooth inclined plane with velocity V from the point A as shown in the figure. The angle of inclination is 45^(@) and the top is connected to a well of diameter 40m. If the body just manages to across the well, what is the value of V? Length of inclined plane is 20sqrt(2)m .

A block of mass m is placed on a smooth inclined plane of inclination theta with the horizontal. The force exerted by the plane on the block has a magnitude
