A rigid body PQR of negligible weight is hinged at P with a force (F) acting at its end R. What will be the angle θ which this force (F) should make with the horizontal to keep the edge PQ of the body vertical?
1
θ = tan-1 (1)
2
θ = tan-1 (2)
3
θ = tan-1 (1.5)
4
θ = tan-1 \(\left( {\frac{4}{3}} \right)\)
