Question 3 Determine the elongation of the square hollow bar when it is subjected to the axial force P = 100 kN, find the permanent elongation of the bar. The bar is made of a metal alloy having a stress-strain diagram which can be approximated as shown.

Please help me answer this asap thank you

The general stress element is loaded such that τxy = 25 MPa. Using Mohr’s circle, find out the maximum normal stress and shear stress acting on this element. (Pure torsion) (Please elaborate what is pure torsion means.)

Consider the state of plain “stress" for the following element. Derive the parametric value for the out of plane "strain" component. Applied tractions B A

(8) The homogeneous bar is supported by a smooth pin at C a cable that runs from A to B around the smooth peg at D as shown. Find the stress in the cable if its diameter is 15mm and bar weighs 6,000 kg. 5m B 5m A

The rigid bar ABC pivots about support B. After application of load P, end C of the rigid bar moves upward by 0.07 in. If the length of bar (1) is L₁-41 in, determine the average normal strain in bar (1). Assume that a-135 in, b-39 in, and c-0.15 in a b C Rigid bar 4 Part 1 * Incorrect Determine the distance that end A of the rigid bar moves downward, if end C moves upward by 0.07 in Answer: in VA i 00361

The rod shown below is of diamater 70 mm and is fixed at one end. It is subjected to 500 N.m and 300 N.m torsional moments as shown. Sketch the distribution of the internal torsional moment along the length of the rod. Also find the torsional shear stress at points A and B, and also the largest shear stress in the rod. Point B is to the left of the 500 N.m torsional moment and A is on the right of it. Round-up your answers to the nearest 1/100th of an MPa. y 35 mm 20 mm 500 N.m 35 mm- 300 N.m Torsional shear stress at A = MPа %3D Torsional shear stress at B = MPа Maximum shear stress = MPa %3D
