Okay I think I get it now. I can substitute the fractions and then use the product trig identities to get a single trig function. Edit: It worked thank you so much. I get the same value as I did with Newton's method but negative. I guess it makes sense because it can happen on both sides of the...

I don't understand the part where you define the angle as phi. If you don't mind, could you explain further please?

Thanks I managed to solve it using Newton's method. I forgot I could just send the constant to the right side of the equation and solve it by finding the zeros. Turns out I said 2 revolutions per second but I misread it and it was actually 0.5 revolutions per second. I get a theta of about 0.887...

here is what I have so far(I used a system of axis tilted by the angle theta):

Yes, this is what I thought too but the problem I have is that I have a sum of a sine and a cosine and I can't isolate theta

I have written the equation I have so far in my original post, but sure I can take a pdf scan of my work and send it here give me a minute or two.

Hi, thank you. The dimensions of the cube are not mentioned so I am guessing that they are negligible. As for the mass, it is not mentioned either in my homework question but the m terms cancel out when I try to solve the problem which means theta probably does not depend on the mass of the cube.

I am trying to solve a problem where we have to find the maximum angle before a cube starts sliding when said cube is placed inside a spinning hollow cylinder (the cylinder is placed horizontally). The radius of the cylinder is 0.4 m, the coefficient of static friction between the cube and the...
