I am just doing: 0.8*2.9^2=6.728

I won't know it until I get it right unfortunately, this is a question from an online task.

I am getting: a[radial]=7.677 m/s/s a[tangential] = 6.728 m/s/s (magnitudes only) These are not giving me the correct answer for overall acceleration.

Would it be that: a(A)=-a(B[tangential]) = -L*ω^{2} As the displacement of A is the negative displacement of B (if considering it B as mass), so a(A)=-a(B) in the tangential direction? This allows me to calculate a(A) without solving simultaneously, which doesn't seem right to me.

Are you implying there's another equation I can get from this?

There's five in my equations, unless one I can work out from something else?: a(A), T1, T2, α(rod), α(pulley) ? Otherwise I think I still need a fifth equation. Thanks for the sign tip, though!

Homework Statement As shown in image. 2. Homework Equations Moment of inertia of pulley = 1/2*M*R^2 Moment of inertia of rod (about end) = 1/3*M*L^2 Acceleration of end of rod in theta direction = L*α Acceleration of end of rod in radial direction = L*ω^2 The Attempt at a Solution...

Eeugh. I think I know what you're getting at but I can't quite grasp it. If the multiples coincide, how do you determine what the period of the overall sin(ax)*cos(bx) function is? o:) Also, there's no limitations on the values of a and b. I'm trying to work out the period in general form for...

I know the period is 2pi/a for sin(ax), and the same (2pi/b) for cos(bx). I'm not sure what you mean about the integer multiple bit? Would you mind explaining a bit more? :)

Homework Statement I'm trying to work out the period of a function of the form sin(ax)*cos(bx), where a =/= b. I'm trying solve how the values for a and b relate to the period. I've graphed a lot of functions, but I'm struggling to notice any patterns. The period always seems somewhat related...
