Question

a mechanic uses a double arm spanner to turn a nut. He applied a force of 15N at each end of the spanner a produces a torque of 60Nm. What is the length of the moment arm of the couple​

Answer 1

Answer:

4m

Explanation:

Torque=F×perpendicular distance

60=15×d

60/15=d

4m=d

Answer 2

A mechanic uses a double arm spanner to turn a nut. He applied a force of 15N at each end of the spanner a produces a torque of 60Nm. What is the length of the moment arm of the couple .

Force applied = 15 N

Torque produced = 60 Nm

Length of the moment arms of the couple = ?

_____________________

Momentum of force = force × distance

=> 60 Nm = 1.5 N × distance

=> Distance = 60 Nm / 15 N = 4 m

Therefore , we can say that the length of the arm = 4 m.
