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.
Continue ReadingA 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.

Full Answer >An output arm is the end of a lever that moves the load up when force is applied to the other end of the lever. The upward force that moves the output arm is the output force.
Full Answer >A first-class lever, in which the fulcrum is between the load and the effort, can aid in work by changing the direction of the force and by increasing the efficiency or mechanical advantage of the force applied. The force exerted on a first-class lever has greater mechanical advantage proportional to its distance from the fulcrum.
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.
