Show that the work done by the driver plate during a stress accumulation phase is W=\frac{2m2g2fd}{k}(fs-fdI'm not sure where to start with this. I am given several equations but can't reach the desired equation.
Fn=ρghA
m=ρA3/2
θ=\frac{fs}{fd}
X=\frac{xG}{2fsρghA1/2}...
Homework Statement
This is my own sketch of the problem. The radii are listed, and the circles are all tangent. I need to find the area of the blue part.
