yea i actually solved it :) never mind

Homework Statement I have a under-damped vibration equation (below) that plots displacement vs time graph. Thing is i need to plot an envelope of the graph and it has to take into account initial speed v0. Homework Equations 1. Equation which plots displacement vs time. x(t)=exp^(-zeta*Wn*t) *...

mg + 2(umN) = 0 ? N=Torque/radius? so Torque=gR/2u = 0.098Nm?

https://www.physicsforums.com/mgc_gloss/latex_images/mgc_gloss_extexpl_39-4.png ? so itll be F=umg . friction force=friction x normal force so you are saying that mg=umg+F ? 1.66=0.833+F; F=0.827N ?

Homework Statement I have this problem. I'm trying to calculate the minimal servo torque for the gripper to hold the part in place. http://img52.imageshack.us/img52/8784/96199865.jpg Mass of load is 170grams. u friction between load and walls is 0.5. the diameter of wheel on which the...
