A single steel strut AB with diameter ds = 8 mm. supports the vehicle engine hood of mass 20 kg which pivots about hinges at C and D [see figures (a) and (b)]. The strut is bent into a loop at its end and then attached to a bolt at A with diameter db = 10 mm. Strut AB lies in a vertical plane.
(a) Find the strut force Fs and average normal stress σ in the strut.
(b) Find the average shear stress Ï„aver in the bolt at A.
(c) Find the average bearing stress σb on the bolt at A.
