A force of magnitude F = 2 N is applied to an object at a distance r = 1 m from the axis of rotation such that r makes the angle θ = 30° with respect to the line of action of the force. What is the magnitude of the lever arm?
- 0.5 m
- 2 m
- 4 m
- √3/2 m
- 4.5 m
A force of magnitude F = 2 N is applied to an object at a distance r = 1 m from the axis of rotation such that r makes the angle θ = 30° with respect to the line of action of the force. What is the magnitude of the torque applied?
- τ = 1 N.m
- τ = 3 N.m
- τ = 2.5 N.m
- τ = 1.5 N.m
- τ = 2 N.m
A rod of length 4 m is free to rotate about one of its ends which has a fixed location. If a force of F₁ = 10 N is applied to the middle of the rod, how much force in the opposite direction of F₁ should be applied to the other end of the rod in order for the rod to remain in equilibrium?
- 5 N
- 10 N
- Depends on the angle which the forces make with the rod
- 2.5 N
- 15 N
