One end of rope is fixed to a vertical wall and other end is pulled by a horizontal force of 20N.The shape of flexible rope is shown in fig. The angle made by tangent at A (fixed point of rope) with downward vertical is 30°. Tension in the string at A in N is 20N

A block fof mass 5kg is suspended by a massless rope of length 2 m from the ceilling. A force of 50 N is applied in the horizontal direction at the midpoint P of the rope, as shown in the figure. The angle made by the rope with the vertical in equilibrium is (Take g=10ms^(-2)m .

One end of a horizontal uniform beam of weight W and length L is hinged on a vertical wall at point O and its other end is supported by a light inextensible rope. The other end of the rope is fixed at point Q at a height L above the hinge at point O. A block of weight alpha W is attached at the point Q at a height L above the hinge at point O. A block of weight alpha W is attached at the point P of the beam as shown in the figure. The rope can sustain a maximum tension of 2(sqrt(2)) W . Which of the following statements is/are correct?

A 10kg body is suspended by a rope is pulled by means of a horizontal force to make 30^(@) by rope to vertical.The horizontal force is

A lawn roller is pulled along a horizontal surface through a distance of 20 m by a rope with a force of 200 N . If the rope makes an angle of 60^@ with the vertical while pulling, the amount of work done by pulling force is

A mass of 10kg is suspended by a rope of length 2.8m from a ceiling. A force of 98N is applied at the midpoint of the rope as shown in figure. The angle which the rope makes with the vertical in equilibrium is .

In the figure a rope of mass m and length l is such that its one end is fixed to rigid wall and the other is applied with a horizontal force F as shown below, then tension at the middle of the string is:

A uniform rope of length 10m is on a smooth horizontal surface. It is being pulled by a horizontal force of 20N at one end. The ratio of tension at a distance of 4m from force end to tension at a distance of 4m from free end is

One end of a string 0.5 m long is fixed to a point A and the other end is fastened to a small object of weight 8 N . The object is pulled aside by a horizontal force F, until it is 0.3 m from the vertical through A .Find the magnitudes of the tension T in the string and force F .

One end of a rope is fixed at a point on the ceiling the other end is held close to the first end so that the rope is folded. The second end is released from this position. Find the speed at which the fold at F is descending at the instant the free end of the rope is going down at speed V.
