DOH! You are correct, jeez, I'm stupid at times.
For the torque at the COM due to the force applied by the belt, is force * position of COM?
Given that the COM will move horizontally a distance x from the origin (O) and vertically a distance of R. Using vectors of i for horizontal and j...
Thanks for that.
part a) and c) your correct, I made a mistake in the post.
part d), there would be no torque about the COM from the weight (W) or the normal force (N), but there would from the force applied by the belt (F)? Is this understnding correct?
part e) We are actually given the...
Homework Statement
A cylinder of radius R, length h, and mass m2 has two ends of mass m1 and radius R. Inside the cylinder is liquid which can be modeled as a solid cylinder of mass M, radius R and length h.
This cylinder is placed onto a routegh surfaced conveyer belt which is...
The question is, What is the expression for da/dx and how would the rate of heat transfer be derived?
'Then integrating gives you a(x) = -q*x/(k*A) + const'. Don't mean to sound thick, but what have you integrated here? Fouriers Law?
I have it in my notes that da/dx = -(a1 - a2) / b, where...
