! Required information The press shown is used to emboss a small seal at E. 200 mm A 60° D The reaction at A is 20° E 400 mm For the same load of P = 300 N, determine the reaction at A. (Round the final answer to two decimal places.) N.

The eye bolt is used to support the load of 5 kip. Determine its diameter d to the nearest 1/8 in and the required thickness h to the nearest 1/8 in of the support so that the washer will not penetrate or shear through it. The allowable normal stress for the bolt is σallow = 21ksi and the allowable shear stress for the supporting material is Tallow=5 ksi. Show the FBD and solution

135 mm 85 mm σ, = -58 MPa E = 105 GPa D = 0.33 Beer & Johnston & DeWolf & Mazurek 2.86 (a) For the axial loading shown, determine the change in height and the change in volume of the brass cylinder shown. (b) Solve part a, assuming that the loading is hydrostatic with Ox= Oy = O₂ = -70 MPa

2) The bolted connection shown in the figure uses SAE grade 8 bolts. The members are hot-rolled AISI 1040 steel. A tensile shear load F = 5000 Ibf is applied to the connection. Assume the bolt threads do not extend into the joint. Find the factor of safety for all possible modes of failure. in- →1ş in→< in in in-18 UNC in

The assembly consists of two A992 steel bolts AB and EF and an 6061-T6 aluminum rod CD. When the temperature is 30°C, the gap between the rod and rigid member AE is 0.1 mm. Assume BF is also rigid.
