Unformatted text preview: Member CB has a square cross-section of 35 mm on each side. w=8 kN/m. 4) (20 pts.) The plastic block of size 50x80x120 on the right is bonded to a rigid support and to a vertical plate to which a 240-kN load P is applied. Knowing that G=1050 MPa for the plastic, determine the vertical deflection of the plate. 5) (20 pts.) The yoke-and-rod connection on the left is subjected to a tensile force of 5 kN. Determine the average normal stress in each rod and the avergae shear stress in the pin A between the members. 6) (20 pts.) The stress-strain diagram for a collagen fiber bundle from which a human tendon is composed is given on the right. If a segment of the Achilles tendon at A has a length of 6.5 in. and an approximate cross-sectional area of 0.229 in 2 , determine the tendon’s elongation if the foot supports a load of 125 lb, which causes a tension in the tendon of 343.75 lb. Reminder: lb is a force unit....
