railway Gujarat Metro SCTO Mock Test 2023 Engineering Mechanics Equilibrium and Friction Equilibrium
The two forces F1 and F2 are acting at point and the angle between them is θ as shown in figure. The resultant force is given by:
1
R = \(\sqrt {F{1^2} + 2F1F2Cos\theta + F2^{2}}\)
2
R = \(\sqrt {F{1^2} + 2F1F2Sin\theta + F2^{2}}\)
3
R = \(\sqrt {F{1^2} + 2F1F2Cos\theta - F2^{2}}\)
4
R = \( \sqrt {F{1^2} + 2F1F2Tan\theta + F2^{2}}\)
