4–50. The tapered member is fixed connected at its ends A and B and is subjected to a load P . Determine the greatest possible magnitude for P without exceeding an average normal
stress of sallow = 4 ksi anywhere in the member, and determine the location x at which P would need to be applied. The member is 2 in. thick.

4–51. The rigid bar supports the uniform distributed load of 6 kip/ft. Determine the force in each cable if each cable
has a cross-sectional area of 0.05 in2,
and E = 31(103) ksi.

4–52. The rigid bar is originally horizontal and is
supported by two cables each having a cross-sectional area of 0.05 in2, and
E = 31(103) ksi. Determine the slight rotation of the bar when the uniform load is supplied.
