945. The press consists of two rigid heads that are heldtogether by the twa A-36 steel 12-mm-diameter rods. A6061-T6-solid-aluminum cylinder is placed in the press andthe screw is adjusted so that it just preses up against thecylinder. If it is then tightened one-half turn, determine theaverage normal stress in the rods and in the cylinder. Thesingle-threaded screw on the bolt has a lead of 0.25 mm.Note: The lead represents the distance the screw advancesakong its axis for one complete turn of the screw.-300 mmso mm-250

Given: The lead, P = 0.25 mm The diameter of the steel rod, d = 12 mm The length of the steel rods,…

5) The bolt has a diameter of 20 mm and passes through a tube with an inner diameter of 50 mm and an outer diameter of 60 mm. If the bolt and tube are made of A-36 steel, determine the normal stress in the tube and bolt when a force of 40 kN is applied to the bolt. Assume the end caps are rigid. 40 kN 160 mm 150 mm 40 kN
The compound wooden beam is connected together by a bolt at B. Assuming that the connections at A, B, C, and D exert only vertical forces on the beam, determine the required diameter of the bolt at B and the required outer diameter of its washers if the allowable tensile stress for the bolt is 1st2allow = 150 MPa and the allowable bearing stress for the wood is 1sb2allow = 28 MPa. Assume that the hole in the washers has the same diameter as the bolt.
Downvote for incorrect answer The connection is made using a bolt and nut and two washers. If the allowable bearing stress of the washers on the boards is (b)allow 2 ksi, and the allowable tensile stress within the bolt shank S is (allow 18 ksi, determine the maximum = allowable tension in the bolt shank. The bolt shank has a diameter of 0.31 in., and the washers have an outer diameter of 0.75 in. and inner diameter (hole) of 0.50 in.
A pivoting cantilevered chair support is proposed for an industrial equipment application. If the maximum person weight is 180 lb, determine the greatest distance the chair can extend from the pivoting support at A. The cantilever is made from 1"x3" aluminum tubing with an allowable normal stress of 20 ksi. Also determine to the nearest 1/8" the diameter of the steel pin at A needed for the chair support to pivot about. Use 10 ksi as the allowable shear stress for steel. 180 1 in. 3 in 2.5 in. --0.5 in. 8 in.

The thin-walled cylinder can be supported in one of two ways as shown. Determine the state of stress in the wall of the cylinder for both cases if the piston P causes the internal pressure to be 65 psi. The wall has a thickness of 0.25 in. and the inner diameter of the cylinder is 8 in.
A.) If the F = { - 200i + 400j } N , determine the force in each member and state if its in compressions or tension. A.) Using the same given, if the members have a square cross-section with a diagonal of 11.31cm and thickness of 1cm, determine the axial stressess and the factors of safety on each of the member, if the maximum allowable tensile strength is 60kPa and the maximum allowable compressive strength is 70kPa NOTE: Complete solution and units, free body diagrams, table data if possible <up voting!>
The steel bracket is used to connect the ends of two cables. If the allowable normal stress for the steel is sallow = 30 ksi, determine the largest tensile force P that can be applied to the cables. Assume the bracket is a rod havinga diameter of 1.5 in.

The A-36 steel drill shaft of an oil well extends 12,000 ft into the ground. Assuming that the pipe used to drill the well is suspended freely from the derrick at A, determine the maximum average normal stress in each pipe string and the elongation of its end Dwith respect to the fixed end at A. The shaft consists of three different sizes of pipe, AB, BC, and CD, each having the length, weight per unit length, and cross-sectional area indicated. Hint: You will need to develop a series of FBDs to establish the necessary functions to integrate to determine the displacement. AAB = 2.50 in.² WAB=3.2 lb/ft 5000 ft B ABC= 1.75 in?
