If the maximum flexure stress is 140 MPa, compute the total force (a) in each cover plate and (b) in each flange. Neglect the weakening effect of the bolt holes. 160 mm 20 mm 20 mm 320 mm 20 mm €20 mm

Given: picture. Find: determine the reactions at the beam supports at A& D for the given loading.

A wooden frame shown below is supported by a tie rod CF and a pin support at A. The diameter of the tie rod CF is 30 mm, and the cross-sectional area of member BD is 900 mm?. The diameters of the pins at A and D are 8 mm and 12 mm, respectively, and each pin is subjected to double shear. If the weight of the bucket hanging from end E is 3 kN, determine (a) The axial stresses in tie rod CF and member BD. (b) The shear stresses in pins A and D. - 0.6 m-0.6 m→ D E 0.6 m V30B 1.2 m F
