Question

Find the torque when the work done to move through an angle 1/4π radian is 3J

Answer 1

Answer:

1/4 × x = 3 joule

x = 3 × 4

x = 12 n/m

Answer 2

GIVEN

θ = 1/4 rad

Work = 3 J

TO FIND

• Torque

SOLUTION

☯ w = Tθ

• W = work done
• T= torque
• e = angle (in radians)

According to the Question :

Work done =Tθ

T=W/θ

• T= Torque = ?
• W = Work = 3J
• θ = angle = V ¼π 

T= 3/(¼π)

Torque =12 Nm
