Homework Statement
A flagpole of mass 25kg and length 2.5m is held in a horizontal position by a cable at 30° from the end of the pole. The centre of gravity is 1.5m from the fixed end.
Determine:
1. the tension in the cable.
2. the vertical component of the force at the fixed end of the pole.
Homework Equations
moment = force x perpendicular distance from a stated point
The Attempt at a Solution
Well I was away for the lesson in which we covered moments, couples and torques etc and I really don't understand. I manage to calculate the length of the cable which I got to be 2.89m but I'm pretty sure this is irrelevent. Can somebody possibly point me in the right direction as where to start?
