m8.23 Pipe AB (with outside diameter and wall thickness specified)
supports a uniformly distributed load w. Determine the reaction
forces at pin A, the axial force in member (1), and the normal
stresses at points H and K, located a specified distance above pin A.

p8.46 A load P = 1,200 N acts on a curved steel rod as shown in
Figure P8.46. The rod is solid and has a diameter d = 15 mm. Assume
that b = 35 mm and a = 175 mm. Determine the normal
stresses produced at points H and K.

p8.48 A 30 mm diameter steel rod is formed into a machine part
with the shape shown in Figure P8.48. A load P = 2,500 N is applied
to the ends of the part. If the allowable normal stress is limited
to 40 MPa, what is the maximum eccentricity e that may be used for
the part?

p8.47 A pulley is supported with the bar shown in Figure P8.47.
The pulley has a diameter D = 5 in., and the tension in the pulley
belt is P = 45 lb. Assume that a = 3 in. and c = 6 in. Determine the
normal stresses produced at points H and K. The cross-sectional
dimensions of the support bar at the section of interest are d =
1.5 in. by 0.25 in. thick.
