Thanks! Haven't had to do a double integral before now.

Homework Statement During the design of a new doppler radar unit, you have two circular plates with radius R = 3 cm and a plate separation of d = 5 mm. The magnitude of the electric field between the plates is given as: E = (700 V/(m sec2))*(1-r/Rp)*t 2 where Rp is the radius of the plates...

Homework Statement A 2.2 kg ball is attached to a 0.638 m long string and is pulled an angle Θ from the verticle such that the center of mass of the ball is raised a distance h=0.22 m from its lowest position. The ball is released and allowed to swing down. a) What is the angular frequency of...

My numbers were off and I managed to solve it using that method. Thanks ehild!

I'm afraid I don't understand what you mean. Do I have to include the torques acting on the right leg in my equation? I thought that I would be able to set up an equation for the torques acting on the left leg and proceed from there. This is the equation I'm currently working with to find the...

Clx is the force applied to the left leg at C in the x direction. Thanks for pointing out the distance mistake, I'll correct that and see how it goes.

Sorry, I meant cos θ = .36/1.35 = 74.534°. I am pretty sure this is the angle I want for my torque equation.

Oops, I have to solve for the tension in the center rod and the Normal forces at points a and E. If I could just get one of those the others would come easily.

This problem has been posted here a couple of times, but I can't finish it off, due to some combination of my failure to sum the torques and working out the geometry. Homework Statement A student is standing on a ladder as shown in the figure to the right. Each leg of the ladder is 2.7 m...

Great, thank you!

I have two homework problems that I've solved, but I can't reconcile the answers. The first problem involved a sphere rolling down the hill, I must find the ratio of the translational kinetic energy to the total kinetic energy. KEtot = KEtrans + KErot = 1/2mv^2 + 1/2Iω^2...
