Question

Constants Part A A metal bar is in the xy-plane with one end of the bar at the origin. A force F (6.54 N)i ( 3.06 N )j is applied to the bar at the point x- 3.81 m, y 3.60 m What is the position vector r for the point where the force is applied? Enter the x and y components of the radius vector separated by a comma Submit Request Answer Part B What are the magnitude of the torque with respect to the origin produced by F? Express your answer with the appropriate units. IA T=1 Value Units Submit Request Answer PartC What are direction of the torque with respect to the origin produced by O +x-direction 0 +y-direction O +z-direction O -z-direction O-y-direction O -z-direction Submit Request Answer

Answer 1

a)

r_x=3.81 m

r_y=3.6 m

b)

Torque is given

T=r x F =(3.81 i +3.6 j) x (6.54 i -3.06 j)

T=-11.6586 k -23.544

T=(-35.2026 k) N-m

Magnitude

|T|=35.2026 N-M

c)

Direction is along -Z-direction
