2. A metal plate is .125 inch thick. What force is required to punch out a square piece 1" x 1"? Th ultimate shear stress of the metal is 37,000 psi, and the ultimate tensile stress is 60,000 psi. (2 Punch Force

Please solve this question in hand wirting step by step.

A steel bar of diameter ? = 52 mm is twisted by torques at the ends. The allowable shear stress is 65 MPa. What is the maximum torque that can be applied?

1. The assembly has the diameters and material makeup indicated. If it fits securely between its fixed supports when the temperature is T; = 70°F, determine the average normal stress in each material when the temperature reaches T2 = 130°F. 304 Stainless steel - 2014-T6 Aluminum -C 86100 Bronze A 12 in. 8 in. D C 4 in. -4 ft- 6 ft- 3 ft

GIVEN: Bar has a cross-sectional area of 4 in? and is placed between two rigid immoveable supports when it is 30.00 inches long at a temperature of -20°F. REQ’D: A) The stress in the bar at 90°F if it were made of steel. Esteel = 10 x 10° psi asteel = 13 x 106/°F B) The final length of the aluminum bar

Describe the Plane Strain and Axisymmetrical Strain.

STRAIN

A rectangular plate is subjected to uniform biaxial stress with x = 90 MPa (tension), oy = -20 MPa (compression), and ₂ = 0. The plate has original dimensions 400 X 800 X 200 mm (x X y X z) and is made of steel with E = 200 GPa and v = 0.3. What are the strains Ex, Ey, and Ez?

Determine (d) variable stress and (e) design factor

Consider the column section below. It has eight #9 bars. The material properties are as follows: fr =4,000 psi, f, = 60 ksi, and E. = 29,000 ksi . The cross-sectional area of a #9 bar is 1.0 in.2². 8- #9 0000 2.5" 44 Axis of bending 20" 15" 2.5" 20" P M If the tensile strain in the reinforcing bars cannot be lower than 0.007 when its nominal moment capacity is reached, using the principles of mechanics to determine the maximum axial load n P, that can be carried by the column. Determine the corresponding nominal moment capacity Mn. (you cannot use any design aid) (Ans: Pn = 246 kips, Mn = 460 kip-ft)
