a lever is resting on a valve. the valve is located 3 in from the end of the lever. the total length of the lever is 9.5 in. a 4 lb force is present at the opposite end of the lever. the force makes a 28 deg angle with the lever. the lever makes a 20 deg angle with the horizontal. I am supposed to find the moment about B, which is the spot where the lever comes in contact with the valve.
the force in the vertical direction is -1.9 and the force in the horizontal direction is -3.5.
i got these by multiplying the magnitude of the force by the cos and sin of the angle. i ended up with an answer of 12.35 lb * in.
is that correct?
