SOLUTION (19.1)
Known: The angle of wrap on the motor pulley is 1600, the slackside tension is
known. The belt friction factor is known. Centrifugal force is to be assumed
negligible.
Find: Determine the torque capacity of the motor pulley.
Schematic and
SOLUTION (11.1)
Known: Two steel plates with Sy = 425 MPa are butt welded together with E70 series
welding rods. The weld length is known.
Find: Determine the maximum tensile load that can be applied to the joint with a
safety factor of 3.
Schematic and G
SOLUTION (7.1)
Known: A 950lb gin pole is supported by a stranded steel cable with known cross
section and modulus of elasticity. As the gin pole is descending at a constant velocity,
an accident causes the top of the cable, 70 ft above the gin pole, to s
SOLUTION (3.1D)
Known: Denitions of the terms stress strength, yield strength, ultimate strength,
elastic limit, proportional limit, modulus of elasticity, and yield point are given in
Section 3.2.
Find: Write denitions of the above terms - see Section
