A unifrom horizontal `200 N` beam `AB` length `L` has two weights hanging from it, `300 N` at `L//3` from end `A` and `400 N` at `3L//4` from the same end. What single additional force acting on the beam will produced equilibrium ?

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.

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.

A rigid mass less rod of length L is hinged at its one end a weight W is hung at a distance l(lt L) from this end. What is force P should be applied upwards at the other end so that the rod remains in equilibrium horizontally ? .

A horizontal uniform rope of length L, resting on a frictionless horizontal surface, is pulled at one end by force F. What is the tension in the rope at a distance l from the end where the force is applied?

A uniform rope of length L resting on a smooth horizontal floor is pulled at one end by a force F.The tension in the rope at a distance L/4 from the end where the force is applied is

Where must a 800 N weight be hung on a uniform horizontal 100 N pole of length L so that a body at one end supports one-third as much as a man at the other end ?

a uniform beam, of length L and mass m = 1.8 kg, is at rest on two scales. A uniform block, with mass M = 2.7 kg, is at rest on the beam, with its center a distance L//4 from the beam's left end. What do the scales read?

One end of uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight N is suspended from its lower end if s is the area of cross-section of the wire the stress in the wire at a height (L)/(4) from its lower end is
