A 15 cm wrench is used to screw in a bolt. If 30 n of force is applied to it at a 45 degree angle, how much torque is applied? (Round to the nearest tenth)

3.18 Nm

Explanation:

Given that:

Radius (r) = 15cm = 15/100 = 0.15m

θ = 45°

Applied force (F) = 30 N

The Torque can be obtained using the relation :

T = rF * sinθ

T = 0.15 * 30 * sin(45)

T = 0.15 * 30 * 0.7071067

T = 3.18198015

T = 3.18 Nm

true tan speed = ang vel x radius

d. air pressure decreases as altitude increases.
