A heavy iron bar of weight `W` is having its one end on the ground and the other on the shoulder of a man The rod makes an angle `theta` with the horizontal What is the weight experienced by the man ?

A heavy iron rod of weight 'W' is having its one end on the ground and the other on the shoulder of a man. The rod makes an angle 'theta' with the horizontal. What is the weight experienced by the man ?

A uniform rod of length L and weight W_(R) is suspended as shown in the accompanying figure. A weight W is added to the end of the rod. The rod rests in horizontal position and is hinged at O. the support wire is at an angle theta to the rod. What is the tension T in the wire ?

A uniform rod of length L and weight W_(R) is suspended as shown in the accompanying figure. A weight W is added to the end of the rod. The rod rests in horizontal position and is hinged at O. the support wire is at an angle theta to the rod. What is the tension T in the wire ?

A board is balanced on a rough horizontal semicircular log. Equilibrium is obtained with the help of addition of a weight to one of the ends of the board when the board makes an angle theta with the horizontal. Coefficient of friction between the log and the board is

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?

Figure shows a man of mass 60 kg standing on a light weighting machine kept in a box of mass 30 kg. The box is haning from a pulley fixed to the ceiling through a light rope, the other end of which is held by the man himswelf. If the man manages to keepthe box at rest, what is the weight shown by the man manages to keep the box at rest, what is the weight shown by the machine? What force should he exert on the rope to get his correct weight on the machine?

A horizontal heavy uniform bar of weight W is supported at its ends by two men. At the instant, one of the men lets go off his end of the rod, the other feels the force on his hand changed to

A mass of 2 kg is kept at one end of a 10 cm long rod, and a mass of 5 kg at the other end. Find the point of suspension for the rod so that it remains horizontal. Neglect the weight of the rod.

A spring of weight W and force constant k is suspended is a horizontal position by tw3o ligth strings attached to its two ends. Each string makes an angle theta with the vertical. The extension of the spring is.
