Force on a concrete Form

Question

The figure is the vertical side of a form for pourd concrete that weighs 140.7 pounds per cubic foot. determine the force on this part of  the concrete form.

Answer 1

Step 1:

The weight density of the concrete is 140.7 pounds per cubic foot.

The depth of the concrete form is 4 ft.

The length of the concrete form is 6 ft.

Force exerted is , where is the weight density, is the depth at a point, is the length at a point.

The depth of the concrete form at a particular point is .

The length of the concrete form at a paticular point is 6.

The depth of the concrete form varies from 0 to 4.

Force exerted on the concrete form is 

Force exerted on the concrete form is pounds.

Solution:

Force exerted on the concrete form is pounds.
