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.Know More
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.Learn more about Motion & Mechanics
An example of elastic force is bungee jumping. The elastic cord creates resistance and imposes a force when the cord is stretched far enough. That elasticity creates the bouncing motion a bungee jumper feels after the initial jump, while the cord works to return to its normal size.Full Answer >
An example of mechanical force is the thrust of an airplane. The airplane's engines make use of a propulsion system, which creates a mechanical force or thrust. Without thrust, an aircraft cannot move in the air.Full Answer >
Instantaneous speed is an object's rate of motion at a particular time period or moment. Recording the speed of a running cheetah exactly 13 seconds after its sprint began would be an example of instantaneous speed.Full Answer >
When a person pushes a box across the floor, he is exerting force on the box. The same is true if he lifts the box, drags the box or hits it with a stick. In all cases, he is applying force to the box.Full Answer >
