The A992 steel rod is
subjected to the loading shown. If the cross-sectional area of the
rod is 100 mm2. Neglect the size of the couplings at B and C. The
elastic modulus and yield stress of A992 steel is 200 GPa and 345
MPa respectively. Determine the displacement of B and A with
respect to point D. (Preserve 2 significant digits after the
decimal point.)

700 kN C- Diagram for Question 3 6 m A tower used for a highline is shown in the figure at the left. If it is subjected to a horizontal force of 700 kN and the allowable stresses are 80 MPa in compression and 180 MPa in tension, what is the required cross-sectional area of each member (there are 7 members)? All members are pin-connected. All dimensions are in metres. Note also that BC and AD are not connected where...
Q6. (a) Three identical fatigue specimens (denoted A, B and C) are fabricated from a non-ferrous alloy. Each is subjected to one of the maximum- minimum stress cycles listed in Table 26 (the frequency is the same for all tests) Table 26 Specimen Omax (MPa) Omin (MPa) A +450 -150 +300 -300 +500 -200 Rank the three specimens in terms of their fatigue lifetimes (highest to lowest). Justify this ranking [5 marks] (b) A cylindrical tie rod of diameter 20...

Two samples made from a material with elastic modulus E 200 GPa are subjected to four loading conditions by applying a force F 20 kN. The first sample is a solid circular bar with a 4 cm diameter. The second sample is another circular 4 cm bar, but with a 3 cm diameter hole bored down the centerline. The undeformed (original) length of both samples is Lo 80 cm ne any stresses are below the elastic limit for the material....

Question#1140Marksl The shaft shown in the figure is rotating at 650 rpm and it receives 5592.75 W through a flexible coupling at its right end. The power is delivered to an adjacent shaft through a single helical gear B having a normal pressure angle of 20° and a helix angle of 15o. The pitch diameter for the gear is 105.1814 mm (4.141 in). A spacer is used to position the gear relative to bearing C. The...
