The Portion Of The Cable Attached To The Spring Is At An Angleof A C 35ac O From The 1783292

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.
