Question

2 forces of magnitude 15 N acts vertically upwards and downwards respectively on the two ends of a uniform rod of length 4 m which is pivoted at iskys midpoint .Draw a figure and determine the magnitude of the resultant movement of force from the pivot. ​

Answer 1

Answer:

Explanation:   please note that force in figure will be 15N on each end not 10N

from diagram force on any end = force * moment arm

   = 15 * 2 = 30 N

Since both forces acts in clockwise direction so total moment of force = 30 +30 = 60N
