Q7.12Multiple correct
Figure 7.5 shows a lamina in x-y plane. Two axes z and z z z ′ pass perpendicular to its plane. A force F acts in the plane of lamina at point P as shown. Which of the following P are true? (The point P is closer to z′-axis than the z-axis.) ˆ.
This question refers to a figure in the original PDF.
- (a)Torque τ caused by F about z axis is along -k
- (b)Torque τ′ caused by F about z′ axis is along -kˆ.
- (c)Torque τ caused by F about z axis is greater in magnitude than that about z axis.
- (d)Total torque is given be τ = τ + τ′ τ′. Fig. 7.5
