The metal stud punch shown in the figure below is designed to create circular shaped perforations on thin metal sheets using the 5 mm (diameter), cylindrical punch located at F. The operator is capable of generating a maximum force of 120 N on the handle. The 120 N 50 mm 100 mm 60° 50 mm handle is connected to the main assembly using a double shear connection pin at A and a short link at B. The pin at A is made of a steel with and allowable shear stress of 50 MPa. The 100 mm B 30 300 mm link is made from A-36 steel and requires a safety factor of 2 to protect against possible overloads. You are required to: 200 mm a) Calculate the internal forces at E b) Calculate the diameter of the pin at A and determine the cross sectional area of link BD, to the nearest multiple of 5 mm and 10 mm? respectively.

Pipe 2 has been inserted snugly into Pipe I. but the holes Tor a connecting pin do not line up; there is a gap s. The user decides to apply either force P:lo Pipe I or force P-, to Pipe 2, whichever is smaller. Determine the following using the numerical properties in the box. (a) If only P{is applied, find Pt{tips} required to close gap s; if a pin is then inserted and Ptremoved, what are reaction forces RAand RBfor this load case?

An inflatable structure used by a traveling circus has the shape of a half-circular cylinder with closed ends (see figure). The fabric and plastic structure is inflated by a small blower and has a radius of 40 ft when fully inflated. A longitudinal scam runs the entire length of the "ridge" of the structure. If the longitudinal scam along the ridge tears open when it is subjected to a tensile load of 540 pounds per inch of seam, what is the factor of safety n against tearing when the internal pressure is 0,5 psi and the structure is fully inflated?
Shown below is a figure of a landing gear configuration on the VS and VD planes (for landing gear the directions V, D, and S are often used instead of x, y and z) This gear unit is assumed to represent one side of the main gear on a tricycle type of the landing gear system. The loading assumed corresponds to a condition of nose wheel up or tail down. The design load on the wheel is vertical and it s magnitude for this problem is 15,000 lbf. Determine the reactions at F, H, and G. The fittings at F and H are pinned and therefore cannot transmit any bending moments. The fitting at G is also a pinned fitting.
Solve the problem. A 11-in. connecting rod in an engine connects the wrist pin of a piston at point A to the end of a second rod at point on the crankshaft. As the piston moves forward and back, the crankshaft is turned counterclockwise around point C. The stroke length of the engine is the distance that the piston travels (one way) with its cylinder. If the stroke length is 4 in., and the engine turns at 600 rpm, write a model representing the distance d (in inches) from A to the center of the crankshaft Cas a function of time t (in minutes). Assume that at t = 0, the piston is at its farthest point from the crankshaft. B B C C B A A stroke length
