Question

What is shear force with examples?

Answer 1

Shear is a vertical force

Explanation:

One example: too many people stand on a deck and the bolts anchoring the deck to the house fail (shear) and the deck & people fall to the ground. That was kind of a gross example, but it happens.

Another: you attach a winch to a bumper instead of to a solid surface on a car and pull it off because the bolts holding the bumper on the car weren't strong enough.

it's a 90 degree force.
