Part A Drawing the free-body diagram of the pulley
The portion of the cable attached to the spring is at an angle of = 35° from the ground. The spring has a spring constant of k = 16.5 kN/m. The
pulley is attached to the ceiling by rod BD that forms an angle 0-62.5° with the ceiling. Draw the free-body diagram of the pulley. Recall that the pulley is
massless.
Start all forces at point B in the center of the pulley. Draw all forces as tensile forces, or pulling forces. All angles should be measured from the
positive x axis. They are positive in the counterclockwise direction. Note - You can click on the attributes button after selecting a vector and
enter angle value of the vector in the angle field.
