A rigid beam of weight W = 800 lb hangs from three equally spaced wires, two of steel and one
of aluminum,
The diameter of the wires is 1/8 in. Before they are loaded,
all three wires had the same length. What temperature increase 47 in all three wires would result
in the entire load being carried by the steel wires only? that is, the aluminum wire would become
slack. Given that cel = 30 x 10° psi, steel = 6.5 x 10-6/F and A = 12x 10-6/F.

A steel tape of nominal length 200 m with a plumb bob of mass 16 kg attached to it was used to measure a length down a shaft as 160.852 m. The mean temperature during the measurement was 4 C. If the tape was standardized to be 200.0014m under a tension of 115 N at 20" C temperature, determine the correct measured length.
The following data may be used:
Mass of tape = 0.07 kg/m
Cross-sectional area of tape= 10 mm
Coefficient of linear expansion a = 11x 10/°C
Modulus of clasticity = 2x 10° Nmm
Acceleration due to gravity 9.807 m's.
1-41. The constants B = 1.357(10-6) N-s/(m² -K!/2) and
C = 78.84 K have been used in the empirical Sutherland
equation to determine the viscosity of air at standard
atmospheric pressure. With these constants, compare the
results of using this equation with those tabulated in
Appendix A for temperatures of T = 10°C and T = 80°C.
