The magnitude of the force needed to supply 100 N m of torque to the bolt is 417 N
Here r = < 0, 0.3, 0 >
F = F < 0, 3, -4 >
T = r F sin θ
If v = < 0, 3, -4 >, θ is the angle between r and v
r . v = r v cos θ
0.9 = ( 0.3 ) ( 5 ) cos θ
Cos θ = 0.6
Sin θ = 0.8
T= r F sin θ
100 = 0.3 F ( 0.8 )
F = 417 N
Torque is a type of force which causes an object to rotate about an axis. Torque is represented as τ. Its unit is N m
Therefore, the magnitude of the force needed to supply 100 N m of torque to the bolt is 417 N
