The 7 m long beam, supported by a cable and resting on a smooth inclined surface at point A, is subjected to 
a 150 KN point load. Determine the position ‘x’ of the point load to maintain equilibrium. Neglect the weight of 
the beam. 

The 2-lb brick slides down a smooth roof, such that when it is at A, it has a velocity of 5 ft/s. Determine the speed of the brick just before it leaves the surface at B, the distance d from the wall to where it strikes the ground, and the speed at which it hits the ground.

Consider a problem in which a car of the mass ‘m’ is moving on a road tilted at an angle from the horizontal. What will be the normal reaction of the surface?
