I think ABCD makes the angle, with B being the end point of the spring and C being the end point of the arm connecting one another. But yes, thanks a lot though I'll figure it out from here :)

One final question, how does the angle ABC come into play though?

1. The mass of the door, the height of the door, length of BC and angle of ABC should be given abitrary values. 2. Gravitation potential energy would be larger when it's opened and smaller when it's closed due to the height. 3. The difference in linear Kinetic energy would be zero and only...

Homework Statement The operation of this garage door is assisted using two springs AB and side members BCD, which are pinned at C. Assuming the springs are unstretched when the door is in the horizontal (open) position and ABCD is vertical, determine each spring stiffness k so that when the...
