Question:
(a) What load Pallow can be supported at the midpoint of the bar (x = a) if the allowable stress in the steel wires is 220 MPa and in the aluminum wire is 80 MPa? (See figure part a.)
(b) What is Pallow if the load is positioned at x = a/2? (See figure part a.)
(c) Repeat (b) above if the second and third wires are switched as shown in figure part b.
