Q.(3) Find the magnitude, direction and position of resultant force from the figure alongside.
Given, angle made by the 60 kN force with the horizontal = 45° angle made by the 80 kN force with the horizontal = 30° Ans: Resultant Force = 148.35 kN α = 63.2° with horizontal The resultant force acts at a distance 1.58 m from point O. (O is the point where 80 kN force acts). x (distance from O to the left) = 1.77m |
