Question #2 [12 marks] 15 mm The Figure shows a steel bar of rectangular cross section (10x40 mm) carries a tensile load P and is attached to a support by means of a round pin of diameter 15 mm. The allowable stresses for the bar in tension and the pin in shear are Gallow -120 MPa and Tallow 60 MPa, respectively. What is the maximum permissible value of 10 mm the load P? 40 mm Question #3 [16 marks] Cross...

P6.010 The mechanism shown in the figure is in equilibrium for an applied load of 25 kN. Specifications for the mechanism limit the shear stress in the steel [G82 Ga] shaft BC to 58 MPa, the shear stress in bolt A to 9u MPa, and the vertical defection of joint D to maximum value of 40 mm. Assume that the bearings allow the shaft to rotate freely. Using L-1.200 mm, -115 mm, and b-225 mm, calculate (a) the minimum diameter...

Consider a cantilevered steel bar shown below. The bar must support a static load P of 900 lb and steel with a yield point of 68 kpsi will be selected for the bar. Assume the selected steel is ductile, even material and the stress concentration can be neglected, but a safety factor of 6.0 should be used. * d = ?

Q2. The figure shows a horizontal steel bar of thickness, 3 mm, loaded in steady tension and welded to a vertical support. Find the load F that will cause an allowable shear stress, Tallow = 140 MPa, in the throats of the welds. For the weldments, the electrodes are specified as E6010. For the electrode metal indicated, what is the allowable load on the weldment?

A load P is supported as shown by a steel pin that has been inserted in a short wooden member hanging from the ceiling. The ultimate strength of the wood used is 60 MPa in tension and 7.5 MPa in shear, while the ultimate strength of the steel is 145 MPa in shear. The diameter of the pin is d= 18 mm and the magnitude of the load is P= 20 KN. NOTE: This is a multi-part question. Once an...
