1.6 (A). An I-seetion girder is constructed from two 80 mm x 12 mm flanges joined by an 80 mm x 12 mm web. Four such girders are mounted vertically one at each corner of a horizontal platform which the girders support. The platform is 4 m above ground level and weighs 10 kN. Assuming that each girder supports an equal share of the load, determine the maximum compressive stress set up in the material of each girder when the platform supports an additional load of 15 kN. The weight of the girders may not be neglected. The density of the cast iron from which the girders are constructed is 7470 kg/m³. [2.46 MN/m².]

The steel tie bar shown is to be designed to carry a tension force of magnitudeP=120 kN when bolted between double brackets at A and B. The bar will be fabricated from 20-mm-thick plate stock. For the grade of steel tobe used, the maximum allowable stresses are σ =175 MPa, τ =100 MPa,and σb=350 MPa. Design the tie bar by determining the required values of(a) the diameter d of the bolt, (b) the dimension b at each end of the bar, and(c) the dimension h of the bar.
Problem 1): A circular pipe girder is constructed from 80mm external diameter and 60 mm internal diameter. Three such girders are mounted vertically one at equal angles of a circular horizontal platform which the girders support. The platform is 5 m above ground level and weighs (0.1*B) KN. The platform supports an additional central load of (0.2*B) KN. The weight of the girders may not be neglected. The density of the material from which the girders are constructed is (290*B) kg/m3. Assuming that each girder supports an equal share of the load, determine the compressive stresses set up in the material of each girder:1- At the lower point of the girder.2- At the middle point of the girder.3- At the upper point of the girder. Discuss the above values when the weights of the girders are neglected.Note: B = 39 Problem 2): A 20 mm diameter steel rod passes concentrically through a bronze tube (200+Q) mm long, 50 mm external diameter, and 40 mm internal diameter.

Two forces P can be applied separately or at the same time to a plate that is welded to a solid circular bar of radius r. Determine the largest compressive stress in the circular bar (a) when both forces are applied, (b) when only one of the forces is applied.
Two wooden members of 80 *120-mm uniform rectangular cross section are joined by the simple glued scarf splice shown. Knowing that β=22° and that the maximum allowable stresses in the joint are, respectively, 400 kPa in tension (perpendicular to the splice) and 600 kPa in shear (parallel to the splice), determine the largest centric load P that can be applied
The lap joint shown is connected by three 16-mm diameter rivets. If the allowable stress for shear in rivets is 40 MPa and bearing between therivets and the plates is 60 MPa determine the safe load P.
Straight rods of 0.30-in. diameter and 200-ft length are sometimes used to clear underground conduits of obstructions or to thread wires through a new conduit. The rods are made of high-strength steel and, for storage and transportation, are wrapped on spools of 5-ft diameter. Assuming that the yield strength is not exceeded, determine (a) the maximum stress in a rod, when the rod, which was initially straight, is wrapped on the spool, (b) the corresponding bending moment in the rod. Use E= 29 * 106 psi.

A horizontal shelf AD of length L=1215mm, width b=305mm, and thickness t=22mm is supported by brackets B and C (Fig A). Note that the shelf is symmetric: AB=CD.
