Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.
In folding, clamping beams hold the longer side of the sheet. The beam rises and folds the sheet around a bend profile. The bend beam can move the sheet up or down, permitting the fabricating of parts with positive and negative bend angles. The resulting bend angle is influenced by the folding angle of the beam, tool geometry, and material ...
An important part of determining bending moments in practical problems is the computation of moments of force. Let F {\displaystyle \mathbf {F} } be a force vector acting at a point A in a body. The moment of this force about a reference point ( O ) is defined as [ 2 ]
In a horizontal beam supported at the ends and loaded downwards in the middle, the material at the over-side of the beam is compressed while the material at the underside is stretched. There are two forms of internal stresses caused by lateral loads:
One side effect of bending the workpiece is the wall thickness changes; the wall along the inner radius of the tube becomes thicker and the outer wall becomes thinner. To reduce this the tube may be supported internally and or externally to preserve the cross section. Depending on the bend angle, wall thickness, and bending process the inside ...
Alee: on or toward the lee (the downwind side). [5] Aloft: the stacks, masts, rigging, or other area above the highest solid structure. [1] Amidships: near the middle part of a ship. [1] Aport: toward the port side of a ship (opposite of "astarboard"). [6] Ashore: on or towards the shore or land. [7]

A press brake bending a sheet of steel. A press brake is a type of brake, a machine used for bending sheet metal and metal plate. [1] It forms predetermined bends by clamping the workpiece between a matching top tool and bottom die.
