Draw a neat labelled diagram to show the direction of two forces acting on a body to produce rotation in it. Also mark the point O about which the rotation takes place.

Draw a neat and labelled diagram of a fish and answer the following questions : what name is given to body which is pointed at both ends ?

A body held completely immersed inside a liquid experiences two forces: (i) F_(1) , the force due to gravity and (ii) F_(2) the buoyant force. Draw a diagram showing the direction of these forces acting on the body and state the conditions when the body will float or sink.

A pulley system has a velocity ratio 5. Draw a neat labelled diagram of the pulley system to lift a load by applying the effort in a convenient direction. Mark the tension in your diagram. If the efficiency of the system is 80% find its mechanical advantage.

STATEMENT-1 : Tension at every point in a string with mass at every cross section must be unequal , if the string is accelerating . and STATEMENT - 2 : If we draw free body diagram for any section of the string , net external force acting on the string has to be equal to product of its mass ( which is non- zero ) and its acceleration .

Draw a labelled diagram of an arrangement of two pulleys, one fixed and other movable. In the diagram, mark the directions of all forces acting on it. What is the ideal mechanical advantage of the system ? How can it be achieved ?

You are given four pulleys and three strings. Draw a neat and labelled diagram to use them so as to obtain a maximum mechanical advantage equal to 8. In your diagram mark the directions of load L, effort E and tension in each strand. What assumptions have you made to Obtain the required mechanical advantage ?

A spring is compressed against a rigid wall. Draw a neat and labeled diagram showing the forces acting on the spring.

A body is supported on a rought plane inclined at 30^(@) to the horizontal by a string attached to the body and held at an angle of 30^(@) to the plane . Draw a diagram showing the forces acting on the body and resolve each of these forces (a) horizontally and vertically, (b) parallel and perpendicular to the plane.

When a body is hinged at a point and a force is acting on the body in such a way that the line of action of force is at some distance from the hinged point, the body will start rotating about the hinged point. The angular acceleration of the body can be calculated by finding the torque of that force about the hinged point. A disc of mass m and radius R is hinged at point A at its bottom and is free to rotate in the vertical plane. A force of magnitude F is acting on the ring at top most point. Component of reaction at the hinge in the vertical direction is
