a) Calculate the reaction forces in terms of F andtheta.b) Calculate the internal shear force and moment as a function of x using cuts and summingforces and moments in terms of F, L, andtheta.c) Calculate the shear force and moments by integration in terms of x, L, F andtheta.d) Assuming a rectangular cross section compute the average normal stress for the case F =10kNat 30° where b =0.04 m, h = 0.08 m, at the point x = L/4, L = 1 m at the centroid.e) With the cross section given above compute the average normal stress for the case F =10kN at30° at the point x = L/4, L = 1 m at each surface of the beam.f) Calculate the shear stress at the top and bottom surface, at the neutral axis and at x = 0.25 mand y = 0.02 m above the neutral axis.

2. A 10 mm diameter cylindrical specimen of an aluminium alloy is loaded in uniaxial tension in a testing machine. a) If the specimen begins to yield at a load of 30 kN, what is the yield stress of the material? b) At the point where yielding begins, the measured increase in length between two points initially 50 mm apart is 0.27 mm. At what strain does yielding occur? c) If the load-deflection curve is linear up to the yield point, what is the elastic modulus of the material? d) If the diameter of the specimen was reduced by 18 um at the yield point, what is the Poisson's ratio of the material?
