Problem 1: The pin in a Box-Pin coupling is acted upon by a force (F), that varies as random variable due to misalignment as (2, 0.08) kN. The load act at a distance (/) that varies as (25 t 3) mm. The diameter of the pin (D) is 18 mm. The fillet radius at the pin shoulder is about 1.5 mm. The stress concentration factor due to fatique in bending is thus a random variable kb that could vary from 1.3 to 1.5. The pin is made of steel AISI 4340 with mean endurance strength in bending of 400 MPa, and a standard deviation of 25 MPa. Determine the pin diameter (d), if one pin in every 10000 may be permitted to fail.

A flange coupling connects two 2” diameter shafts. The flanges are fitted with 6 bolts of SAE 1040 steel on a 7” bolt circle. The shafts runs at 300 rpm and transmits 45 hp. Assume a factor of safety of 5, ultimate tension of 70,000 psi, and ultimate shear of 55,000 psi.

A 0.5-in.-diameter steel [E= 30,000 ksi] bolt (1) is placed in a copper tube (2). The copper [E= 16,000 ksi] tube has an outside diameter of 1.00 in., a wall thickness of 0.125 in., and a length of L= 8.0 in. Rigid washers, each with a thickness of t= 0.125 in., cap the ends of the copper tube. The bolt has 20 threads per inch. This means that each time the nut is turned one complete revolution, the nut advances 0.05 in. (i.e., 1/20 in.). The nut is hand-tightened on the bolt until the bolt, nut, washers, and tube are just snug, meaning that all slack has been removed from the assembly but no stress has yet been induced. What stresses are produced in the bolt and in the tube if the nut is tightened an additional quarter turn past the snug-tight condition?
A right angled bell crank lever is to be designed to raise a load of 5 kN at the short arm end. The lengths of short and long arms are 100 and 450 mm respectively. The lever and the pins are made of steel 30C8 (S = 400 N/mm2). And the factor of safety is 5.the permissible bearing pressure on the pin is 10 N/mm². The lever has a rectangular cross section and the ratio of width to thickness is 3:1. The length to diameter ratio of the fulcrum pin is 1.25:1. Calculate (i) The diameter and length of the fulcrum pin (ii) The dimensions of the cross section.
A semi-elliptic spring used for automobile suspension, consists of two extra full-length leaves and eight graduated-length leaves, including the master leaf. The centre-to centre distance between the two eyes is 1 m. The leaves are made of steel 55Si2Mo90 (Syt = 1500 N/mm2and E = 207000 N/mm2) and the factor of safety is 2. The maximum spring load is 30 kN. The leaves are pre- stressed so as to equalize stresses in all leaves under maximum load.

The allowable shear stresses of the shaft, key and bolt materials are 60 MPa, 50 MPa and 25 MPa respectively. The shear modulus of the shaft material may be taken as 84GPa. The angle of twist of the shaft should be limited to 1 degree in 20 times the shaft diameter. Note: show complete solution
