Document Summary
In many situations a surface area of a body is subjected to a distributed load. Such forces are caused by winds, fluids, or the weight of items on the body"s surface. The intensity of the load is defined as the pressure , which is defined as the force per unit. In such cases, if the pressure is uniform across the plate, then if we multiply the pressure by the width of the plate we can write. : a function of and has a units for force per length. The net force acting on the plate is found by integrating over the length of the plate to. The magnitude of the force acting on the element is equal to give. The force will produce a moment about point given by plate, which yields. Hence, the magnitude of the resultant force is equal to the total area under the loading curve.
