Angular Momentum
The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…
Moment of a Force
The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…
Question

I push down on a wrench with 35lbs of force, 8 inches from the but I'm trying to break free. How many lbs-ft of torque am I generating? 

Expert Solution
Check Mark
Step 1

 Given,
Force, F= 35 lbs, and length, l= 8 in=0.67 ft.

Step 2

The torque generated is given by,

τ=l×F×sin θ

where l= length, F= force applies, and θ= angle between force and axis.

Putting the values we have,

τ=l×F×sin θ=0.67 ft×35 lbs×sin 90=23.45 lbs-ft
