In the figure shown the force with which the man should pull the rope to hold the plank in position is `F` . If weight of the man is `60kgf` , the plank and pulleys have negligible masses, then.

In the given diagram, with what force must the man pull the rope to hold the plank in position? Weight of the man is 60 kg. Neglect the weight of plank, rope and pulley.

In the given diagram, with what force must the man pull the rope to hold the plank in position? Mass of the man is 80kg. Neglect the weights of plank, rope and pulley. Take.

With what force must a man pull on the rope to hold the plank in position it the man weights 60 kg? Neglect the weight of the plank, rope and pulley ( Take g= 10m//s^(2))

A block of mass M is tied to one end of a massless rope the other end of the rope is in the hands of a man of mass 2M as shown in the figure the block and the man are resting on a rough plank of mass M as shown in the figure the whole system is resting on a smooth horizontal surface the man pulls the rope pulley is massless and friction what is the displacement of the plank when the block meets the pulley ( Man does not leave his position on plank during the pull)

A block of mass M is tied to one end of a massless rope the other end of the rope is in the hands of a man of mass 2M as shown in the figure. The block and the man are resting on a rough plank of mass M as shown in the figure. The whole system is resting on a smooth horizontal surface. The man pulls the rope. Pulley is massless and frictionless. What is the displacement of the plank when the block meets the pulley ( Man does not leave his position on plank during the pull)

A man of mass M stands on a.box of mass m as shown in the Fig. 2E. l (a). A rope attached to 'the box and passing over an overhead pulley allows the man to raise himself and the box by , pulling the rope downward. (i) With what minimum force should the ' man pull the rope so as to prevent himself , from falling down. (ii) If the man pulls the rope with a force F greater than the minimum force, then determine the acceleration of the (man + box) system. (iii) Determine. the normal reaction between the man and the trolley.

A plank of mass M is placed on a rough horizontal force F is applied on it A man of mass m rens on the plank find the acceleration of the man so that the plank does not move on the surface . The coefficent of friction between the plank and the surface is mu Assume that the man does not slip on the plank

A man of mass 60kg is standing on a massless weighing machine. Find the weight of the man in different situations as shown in the following figures. Man holds the rope and the block is at rest. Man holds the rope and the system is at rest. Man holds the rope and the system is at rest.

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?
