A 30-mm thick AISI 1020 steel plate is sandwiched between two 10-mm thick 2024-T3 aluminum plates and compressed with a bolt and nut with no washers. The bolt is M10 x 1.5. property class 5.8. (a) Determine a suitable length for the bolt, rounded up to the nearest 5 mm. (b) Determine the bolt stiffness. (c) Determine the stiffness of the members.

A pushrod in the valve mechanism of an automotive engine has anominal length of 203 mm. If the rod is made of SAE 4140 steel,compute the elongation due to a temperature change from -20ºC to140ºC.

A tensile load of 330,000 N is applied to a copper pipe with maximum allowable stress of 110 MPa and 80 mm inner diameter. What should be the thickness of the pipe?   Choices: A. 9.78 mm B. 12.35 mm C. 11.56 mm D. 10.55 mm

Te - Effective throat thickness well in mm = 6 sin45° Consider the following drawing in which plate 1 is welded onto plate 2 as shown for tensile and shear loading. The plates are fillet welded with a weld thickness of 6 mm as shown for a length of 150 mm.   The plates have an ultimate strength of 275 MPa and the welding was done with F70 welding electrodes, which possesses an ultimate strength of 483 MPa.   Consider a partial factor of safety of 1.7 for the welded joint and determine the design strength of the weld joint, both in tension (Tdw) and in shear (Vdw) due to the forces acting on it.   a)      Determine the design strength of the following weld in tension ( ) due to vertical forces. b)      Determine the design strength of the weld in shear ( ) due to horizontal forces.   Attached pic is shear equation for calculation Tension equation for calculation is: Tdw = FyLwte /Ymw

11.16 Two 20-mm steel plates are butt-welded together. Both the plate and the welding electrode materials correspond to strength properties of Su = 500 MPa and S, = 400 MPa. The imposed loading fluctuates rapidly between -20 and +60 kN. Estimate the length of weld required in order to provide a safety factor of 2.5: (a) If the weld reinforcement is not removed. (b) If the excess weld material is carefully ground off to provide smooth, continu- ous surfaces.
