QUESTION 1 1.1 A bar with cross-section 4 cm x 4 cm is subjected to an axial pull of 28 KN. Calculate the normal stress and the shear stress on a plane at an angle of 60° with the axis of the bar, the plane being perpendicular to one face of the bar. 1.2 Find the moment-carrying capacity of a rectangular section with dimensions 100mm x 40mm. The material has a permissible stress of 90MPa in both tension and compression. 1.3 At a point in a material the two-dimensional stress system is defined as shown in figure 1 below. Calculate the principal stresses and the maximum shearing stresses on the oblique plane. 90 MPa 60 MPa 400 Figure 1 30 MPa

You are given a metal rod, cut to a length of 12 in plus/minus .25in. Then you need to cut off 2 in with an accuracy of plus/minus .25 tolerance. You end up with a 10 in rod but what is the tolerance? (hint: rely on the basic principle of tolerance
Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N.
