The member is supported by a pin at A and
cable BC. Determine the components of reaction at these
supports if the cylinder has a mass of 40 kg

Thanks for the help! I was wondering why we don't need to take cross products? We were generally taught to use cross products for moments.

[@ItsLexrr]

There is a mistake in the Calculation of the moment, the x component will turn clockwise relative to moment of z which in our case is negative (because we are taking c.cw +) and the y component will turn Counter C.W which is + and u put negative so you need to flips the signs. Why did we have Max and Maz I really didn't get it please explain

[@joevandas2662]

So why is there a support reaction Ay. The pin shouldnt be resisting movement in that direction.

[@fouadayoub1285]

because even though the pin allows the bar to rotate along the y axis, it does not move freely along the y axis.

Super

I really don't understand why the T value in the sum of moment y is negative. Can someone explain?

[@emilianohorta9040]

He made a mistake

[@ChrisPsenica]

Your answer for the moment about z is correct, but you flipped your signs in the equation. It should be -.857t(1)+.4286t(3)
