I've been trying to find the answer for a good hour and a half now.
It involves a 1200 N uniform boom that is supported by a cable perpendicular to the boom. The cable makes a 25 degree angle to the horizontal and hooks up at 3/4 of the entire length of the boom. The boom hinges and makes a 65 degree angle to the horizontal. There's a weight that hangs from the top of the boom that's 2500 N. I'll try to illustrate it a bit:
|
| _
|..._
|..._ ../|
|.../ |
|.../ []
____/
(at least as good an illustraton as my physics teacher can make)
I need to find the tension of the cable that connects the boom to the wall and the horizontal and vertical components of the reaction force exerted on the boom by the hinge. I don't really need an answer, just an explanation of how to find them. Any help is greatly appreciated.
