The question asks for the magnitude and direction at the pin
aand int the cable bc needed to support a 500-lb ball load. the
boomweight ab is neglected. ab is 8ft long and angled at 35degrees.
the cable bc has an angle of 22 degrees and the500-lb ball hangs
from b. a and c are stationary.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
