A uniformly distributed load has a constant value, for example, 1kN/m; hence the "uniform" distribution of the load. Each uniformly distributed load can be changed to a simple point force that can be used to determine the stresses in an object.
A UDL, or uniformly distributed load, can be drawn by using arrows and lines. First, the vectors must be drawn along where the load acts and must be connected with tails. A single line must connect the vectors together and represent the force point. The line should be horizontal.
Sometimes, people are asked to work out the forces and simplify the distributed load to a single point force. To change the uniformly distributed load to a point force, a person will first need to know the total force and the location that the total force will act through. Then, the person will need to find the areas that are enclosed by the object that is being analyzed. The person will need to view the left, right, and top sides of the UDL. Next, multiply the force applied per meter by the length that the force acts over and the entire force will be determined. To find the point force, the centroid area, or direct center of the load, will need to be determined. That is the point force.

According to Briggs and Stratton, a governor is like a car's cruise control system, as it keeps the engine running at the same speed.
Full Answer >Every forklift maintains its balance while carrying a load by using a cantilever system positioned on a fulcrum, which is the machine's front wheel axle. The cantilever system is similar to a simple teeter-totter, a device that also relies on a fulcrum to operate.
Full Answer >According to Mediahex, a wheel and axle makes work easier by changing the amount of force applied to a load. The object that is being moved is a load located at the axle. A force applied at the outer edge of the wheel moves the load. This allows the user to apply the force over a greater distance with less effort than applying force directly to the axle, explains Mediahex.
Full Answer >A class 2 lever is a lever with the fulcrum or joint at one end, with the load that is being carried in the middle. The effort, which is the object lifting or pulling the lever, is at the opposite end from the fulcrum.
