The two structural members, one of which is in tension and the other in compression, exert the indicated forces on joint O. Determine the magnitude of the resultant R of the two forces and the angle θ which R makes with the positive x-axis. The angle θ is measured counterclockwise from the positive x-axis. 2.1 kN 1.5 kN 35。 67 3 Answers: R =T2.70 kN θ = T180.44

C1.3 The truss ABC has an overhang b, and its two members are
inclined at angles a and y to the horizontal, both angles being
positive. A downward vertical force P acts at A. The working
stresses for the members are st in tension and sc in com- pression.
Given b, P, a, st, and sc, construct an algorithm to plot the
required vol- ume of material in the truss against y from y 1⁄4 0
to 75 . Assume...
