can you solve it for me, step by step with the correct answer.. so i can understand what your talking about and using the same strategy for the next 5 problems.

the formula is t(net external)=I(moment of inertia) x a (angular acceleration). i still don't know how to identify and plug in the values.

oooh so it would be 12x2xsin30=18 8x5sin30=20 18+20=38 (i'm sorry I am really not good at this)

i don't know how to find the x and y components to tell you the truth. so should my process be: 12x2xsin30=18 8x3xsin30=-16 18-16=2Nm?

The horizontal beam in the figure below weighs 140 N, and its center of gravity is at its center. http://session.masteringphysics.com/problemAsset/1026448/22/yg.10.59.jpg Find the tension in the cable. Find the horizontal and vertical component of the force exerted on the beam at the...

ok. am i on the right track? 12x3xsin30=18 8x2xsin90=16 18+16=34Nm?

Calculate the net torque about point for the two forces applied as in the figure below The rod and both forces are in the plane of the page. torque= ? Nm http://session.masteringphysics.com/problemAsset/1026433/5/yg.10.42.jpg i know that F2 = 0 since its pointing through point 0...

Second question: A dock worker applies a constant horizontal force of 80.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves 12.0 m in the first 6.00 s. What is the mass of the block of ice? m=?kg please help me

hello I'm having trouble with this question. Hanging Chandelier A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction)...
