Question

Exercise 10.1 Calculate the torque (magnitude and direction) about point O due to the force F in each of the cases sketched in the figure (Figure 1) . In each case, the force F and the rod both lie in the plane of the page, the rod has length 4.00 m, and the force has magnitude 17.0 N. Part A Calculate the magnitude of the torque in case (a). |tau|= N.m Part B Find the direction of the torque in case (a). Into the page Out of the page To the right Upward The torque is zero Part C Calculate the magnitude of the torque in case (b) |Tau|= N.m Part D Find the direction of the torque in case (b). Into the page Out of the page To the right Upward The torque is zero

Explanation / Answer

E) T = r*F*sin(theta)

= 4*17*sin(30)

= 34 N.m

F) out of the page

G) T = r*F*sin(theta)

= 2*17*sin(60)

= 29.44 N.m

H) in to the page
