A thin horizontal bar AB of negligible mass and length l is hinged to a vertical wall at A and supported at B by thin wire BC which is tied to a point C vertically above in the same wall.BC makes angle `theta` with the horizontal . A weight W is moved along the bar. Show how the tensile force T in the thin wire changes with the distance x of the weight from the wall.

In figure a thin horizontal bar AB of negligible weight and length L is pinned to a vertical wall at A and supported at B by a thin wire BC that makes an angle theta with the horizontal. A weight W can be moved anywhere along the bar; its position is defined by the distance x from the wall of its centre of mass. As a function of x, the horizontal component of the reaction at the hinge A is?

A mass M is suspended by a rope from a rigid support at A as shown in figure. Another rupe is tied at the end B, and it is pulled horizontally with a force. If the rope AB makes an angle theta with the vertical in equilibrium then the tension in the string AB is

The x-t graph of particle moving along a straight line is shown in figure Two projectiles A and b are thrown will the same speed such that A makes anle theta with the horizontal and B makes angle theta with the vertical, then

An object of mass m is tied to a string of length l and a variable horizontal force is applied on it which is initially is zero and gradually increases until the string makes ann angle theta with the vertical. Workdone by the force F is

A uniform horizontal beam of length L and mass M is attached to a wall by a pin connection. Its far end is supported by a cable that makes an angle theta with the horizontal . If a man of mass 'm' stands at a distance l from the wall , find the tension in the cable in equilibrium.
