उत्तर
It is easier to turn the steering wheel of a large diameter than that of a small diameter because less force is applied on the steering of large diameter which is at a large distance from the centre of the rim.

A body is acted upon by two forces of magnitude F but in opposite directions. State the effect of the force if both forces act at the same point of the body.
Two forces each of magnitude 10 N act vertically upwards and downwards respectively at the two ends A and B of a uniform rod of length 4 m which is pivoted at its midpoint O as shown in the figure. Determine the magnitude of the resultant moment of forces about the pivot O.
What is the work done when no net force is applied on the body?
A wheel of diameter 3 m is shown in fig. 2 with axle at 0. A force F = 8 N is applied at Q in the direction shown in figure. Calculate the moment of force about:

(ii) point p.
Fig. 5 shows a uniform meter scale weighing 200 gf. Provided at its centre. Two weights 300 gf and 500 gf are suspended from the ruler as shown in the diagram. Calculate the resultant torque of the ruler and hence calculate the distance from mid-point where a 100 gf should be suspended to balance the meter scale.
State whether the moment of force is a scalar or vector quantity?
State one factor on which the magnitude of a non-contact force depends. How does the magnitude of a non-contact force change along with distance?
