Sorry about that, should be fixed.

Homework Statement I am trying to solve for change in velocity for the center of a rim with respect to the contact patch of a tire that has some degree of camber. The equation finalized is shown in the image below, equation 2.6. http://imgur.com/a/oHucp Homework EquationsThe Attempt at a...

just in case anyone comes across this... δ1 is actually x-rθ and δ2 is x+rθ... then ΣF=ma turns into -k(x-rθ) - mg + k(x_in-x-rθ) = mx". do the same for rotation and torques then solve

Homework Statement Thin uniform disk with radius r, mass m, and moment of inertia 0.5mr2 is suspended from a cable line where one end is attached to a set point via a spring, and the other end is also attached to a spring but is moving in an upwards direction. Solve for the equations of motion...

Homework Statement http://imgur.com/a/X7mWA Homework Equations 1. ΣF = m a 2. Στ = Iθ" The Attempt at a Solution First , assuming small motion, all movement of the scale can disregard x components (so the spring stretches only in vertical direction without an impact from the x directional...

Ahh, i forgot, when using v = w x r you have to always measure from from IC unless using relative velocity equation. Thank you!

Homework Statement Homework Equations v = w x r The Attempt at a Solution I got the answer correct after a few tries, but I am little confused on why it has to solved this specific way. I know that v = w x r, so why can I not just say w = v/r? Is it because w is measured from the center of...

Thank you for helping! Sorry there was such a delay in my response. Yes it ended up being just a calculation error when mixing up the signs!

Homework Statement Determine the angular velocity of the gear at the instant shown. Set v = 9ft/s and vc = 6ft/s. Assume counterclockwise is positive. Homework Equations v = w x rIC The Attempt at a Solution I tried solving this many times using va = v0 + (ω x ra0 ) and vb=v0 + (ω x rb0 )...

You slick guy you... compressing or extending. Makes sense now. Thanks.

Homework Statement The masses of blocks A and B are 2 kg and 3 kg, respectively. Block A slides to the right on the smooth surface and strikes the spring attached to stationary block B. The spring deforms during the collision process. What quantity do the blocks have in common at the instant...

Oh... my bad

If you do that then you will have two components of acceleration (in the x AND y direction) and so your definition of N would involve more variables than the ones they allow, or at least would involve a lot more manipulation to isolate N.

Convert km/h into the same units as your acceleration - so if using 9.81m/s2 convert km/h into m/s. You are only dealing with one direction so there isn't a reason to apply any conversion of degrees.

Homework Statement Small mass sits on a circular revolving table, 200 mm from center. It is given a constant angular acceleration of 2 rad/s. The static coefficient of friction is 0.2. At what angular velocity will the mass start to slip? Homework Equations ar=v2/r ar=r''-rθ'2 aθ=rθ''+2r'θ'...
