I just tried multiplying it by sin(16), which of course didn't work, but dividing by it sure did work. Thanks.

Homework Statement Blocks A and B are connected by a cable that passes over support C. Friction between the blocks and the inclined surfaces may be neglected. Knowing that motion of block B up the incline is impending when mB = 4.5 kg, determine: (a) the coefficient of static friction...

Equation (2) comes from the loop rule. I know that the current running through R1 is i1 and the current running through R2 is i2. These two currents add up to the main current i3. The equation would be i3 = i1 + i2. At the moment the currents i1 and i2 run through R3, they add up together to...

Where the Equations Came From I'm following along with the solution manual on this one. For this part, the book said, "The symmetry of the problem allows us to use i2 as the current in both of the R2 resistors and i1 for the R1 resistors. We see from the junction rule that i3 = i1 – i2. There...

Figure Associated With Problem Oops. Forgot to upload the drawing. Sorry. It's up now.

Homework Statement In the figure ε = 15.1 V, R1 = 1560 Ω, R2 = 2130 Ω, and R3 = 4210 Ω. What are the potential differences (in V) (a) VA - VB, (b) VB - VC, (c) VC - VD, and (d) VA - VC? The figure consists of single ideal batter connecting to a diamond shape circuit ABCD. Going clockwise...

Thanks for all the help.

Here is some additional information. Can be solved using F=ma in the x and the y direction. Study, for example, the bottom right cylinder. In the y direction, you have the weight of the cylinder, the y-component of the friction, between the top cylinder and the bottom right cylinder, the...

I know the forces working on the penny in the y-axis are the normal F = Weight. What I've been thinking about doing is using mgh = (1/2)m(V^2) My problem is the h. I'm thinking about saying that the center of the sphere is 0, and that the initial height of the penny is the radius. After...

Homework Statement A penny is released from the top of a very smooth sphere of radius 1.3 meters. The sphere is fixed to a platform and doesn't move. The penny slides down from rest and leaves the sphere at a certain point. How far will the penny fall away from the point of contact of the...

Homework Statement Use a double integral to find the area of one loop of the rose r = cos 3\theta Homework Equations The Attempt at a Solution This is a past test question. The only thing I got wrong was the set up while I got the rest of the mechanical steps right. I set up as...

Yeah. The surface they are on top definitely is horizontal and from looking at the drawing provided, the cylinders are in fact rough enough to stay on top of each other without slipping. I may be over thinking it.

Homework Statement Three cylinders with the same size, density, and structure are piled on each other and on top of a rough surface. Find the minimum angle which the direction of the force acting between the cylinders and the rough surface makes with the vertical? The cylinders are stacked...
