The portion of the cable attached to the spring is at an angle of *A??c*=35Acˆ?o from the ground. The spring has a spring constant of *k*=14.5 kN/m . The pulley is attached to the ceiling by rod *BD* that forms an angle *A?¸*=62.5Acˆ?o with the ceiling.

1) Find the weight of the hanging mass when the spring, with spring constant 14.5kN/m , has been stretched 12.7cm . The tension in rod *BD* is3267 N . Recall that the pulley is massless.

Express your answer to three significant figures and include the appropriate units.

Determining the displacement of a spring

The cable segment attached to the spring is at an angle of *A??c*=50.0Acˆ?o from the ground. The spring has a spring constant of *k*=14.5 kN/m . The pulley is attached to the ceiling by rod *BD* that forms an angle *A?¸*=70.0Acˆ?o with the ceiling. The hanging mass causes a tension of 3461 N in rod *BD*. What is the displacement of the spring?

Express your answer to three significant figures and include the appropriate units.
