inky, what are those 4 forces exerted on right leg? I got 3
1 is on C from the left leg, which has negative Y component and positive X component
2 is on E from the ground, which only has a positive Y component
3 would be the tension
the same for the left leg, I got 4 forces
1 is on C from...
I misunderstood the problem, and the answer is the correct one! sorry, and someone can close this post if necessary
Homework Statement
A stick of uniform density with mass M = 7.9 kg and length L = 1 m is pivoted about an axle which is perpendicular to its length and located 0.15 m from one...
"There should only be two forces acting on the mass."
"Alternatively, you can divide the string tension into orthogonal components."
"But right now you're essentially dividing by a cosine when you should be multiplying by one."
those were the key points :)
well, I understand what you are saying and that's exactly what I did... I draw an Inclined plane in which the direction of Y is the direction of the upper string, and the origin would be right in the mass. The acceleration I was talking about was the centripetal acceleration, which, if you look...
