Concept explainers

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

Question

An industrial roller door is a uniform rectangular panel made of a heavy material, y = 45 pcf, and rolls along
the fixed rail D on its hanger-mounted wheels at A and B. The door is maintained in a vertical plane by the
floor-mounted roller C which bears against the bottom edge. For the position shown, compute the
horizontal side thrust (x-direction) on each of the wheels A and B that must be considered in designing the
brackets. The door has a thickness, t = 2 in, and is made of solid material.

Problem 05: The circular disk of 200 mm radius has a mass of 25 kg, and centroidal radius of gyration k-175 mm. The disk has a concentric circular groove of 75 mm radius cut into it (it's like a big yo-yo). A steady force T is applied at an angle 0 to a cord wrapped around the groove as shown. If T-30 N, 0-0, μs-0.10, and μk=0.08, determine the angular acceleration a of the disk, the acceleration ac of its mass centre G, and the friction force F which the surface exerts on the disk. m = 25 kg k = 175 mm H₂ = 0.10 H=0.08. 200 mm 75 mm -- Problem 6/89 T

The figure below shows a small gate attached to two couplers. The door needs a resultant moment of 178 N-m counterclockwise to be able to open when rotated around pivot A. The purpose of this problem is to calculate the force F2 needed for the door to open with the specified moment. The magnitude of the force F1 is equal to 480 N (Note that due to the distances provided, it is not necessary to use the principle of moments for couples and not all dimensions will be needed). What is the magnitude of the force F2 necessary for the gate to open? This will be the answer that will be offered in the numerical entry of this question.
