Name the factors affecting the turning effect of a body
A half metre rod is pivoted at the centre with two weights of 20gf and 12gf suspended at a perpendicular distance of 6 cm and 10 cm from the pivot respectively as shown below.
1) Which of the two forces acting on the rigid rod causes clockwise moment?
2) Is the rod in equilibrium?
3) The direction of 20 kgf force is reversed. What is the magnitude of the resultant moment of the forces on the rod?
State two effects of a force when applied on a body.
A potter turns his wheel by applying a force through the stick near the rim of wheel.
Find the moment of force of 20 N about an axis of rotation at distance 0.5 m from the force.
Calculate the acceleration produced in a body of mass 50 g when acted upon by a force of 20 N.
State two factors affecting the turning effect of a force.
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?
Assertion & Reasoning
- Assertion: The sum of the clockwise moments is equal to the sum of the anticlockwise moments.
- Reason: The principle of conservation of momentum is valid if the external force on the system is zero.
