Question

Exercise 10.6 A metal bar is in the xy-plane with one end of the bar at the origin. A force F (6.56 N )i -2.70 N)j is applied to the bar at the point a 2.54 m, y 3.22 m. Part A What is the position vector T for the point where the force is applied? Enter the x and ycomponents of the radius vector separated by a comma.

Explanation / Answer


F = (6.56) i +(-2.7) j

Part A; r = 2.54i +3.22 j

rx,ry = 2.54 , 3.22 m


Part B:

T = rxF

T = (2.54 i +3.22 j) x (6.56 i -2.7 j)

T = (-2.54*2.7k - 3.22*6.56 k)

T = - 27.98 k N.m

Magnitude of torque = 27.98 N.m

Part C: - z direction
