Problem 2. Liquid concrete is poured into the form (R = 0.313 m). The form is w=4.25 m wide normal to the diagram. Compute the magnitude of the vertical force exerted on the form by the concrete, and specify its line of action. p = 2.5PH20 Fy Concrete dF Note: S sin@cosode=cos20 s20+ constant 1 sin20cosode=sin0+ constant 1 sin20de=(0-sinocos0) + constant
