Question

A wedge with a base (x) of 2 ft, height (h2) of 5 ft, and width into the page of 7 ft is holding back water 7ft deep (h1). Determine the weight of the block necessary to prevent the gate from opening.

Answer 1

Answer:

hello your question lacks the required diagram attached below is he missing diagram and solution

answer : 17480.618 Ib

Explanation:

To calculate the weight of block neccessary to prevent the gate from opening , we will first calculate  the force of water from the hinge

next we will calculate moments about the force of water and the force about the hinge of the gate

attached below is the complete solution and free hand sketch

from the sketch : h1 = 7 ft, x = 2ft, h2 = 5ft,
