For example, in a standard barbell bench press, the right arm may perform 55% of the work and the left arm 45%. However, if the right or left arm is used singularly, then it can be assured that each arm is performing 100% of the work for that respective lift. This can mean that the strength of the right and left arms develops more evenly. [11]

A schematic image of three types of cantilever. The top example has a full moment connection (like a horizontal flagpole bolted to the side of a building). The middle example is created by an extension of a simple supported beam (such as the way a diving board is anchored and extends over the edge of a swimming pool).
The poles of magnets were positioned as a checkerboard array to fit the magnetic field generated by the PCB platform. The robot can be built in different size depending on the size of the array. Prototypes tested in SRI papers are mainly 2*2, [28] [29] [31] 3*3, [29] and 5*5 [31] squares.

[12] Diagram 3 shows that now three rope parts support the load W which means the tension in the rope is W/3. Thus, the mechanical advantage is three. By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff ...
In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
In the mid-1990s, the arm control system was redesigned to increase the payload capability to 586,000 pounds (266,000 kg) in order to support space station assembly operations. [9] While able to maneuver payloads with the mass of a loaded bus in space, the arm motors cannot lift the arm's own weight when on the ground. [ 3 ]
