Name the factors affecting the turning effect of a body
Less force is needed when applied at a farther distance from the pivoted point.
What are contact forces? Give two Example
Three forces A, B and C are acting on a rigid body which can turn about O in fig.9. If all the three forces are applied simultaneously, in which direction will the body move? Explain.
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?
How does the distance of separation between two bodies affect the magnitude of the non-contact force between them?
State when the moment of force is positive and when it is negative.
What is meant by the term ‘moment of force’? If the moment of force is assigned a negative sign then will the turning tendency of the force be clockwise or anti-clockwise?
Write the expression for calculating the moment of force about a given point.
