I am trying to solve the problems on a sample exam, I am stuck on Problem 2, can anyone help? I can't get to help until tomorrow!

Thanks!

sum the forces in y, and the moment about point 1

define the point at which w1 acts as point 1, x=0
define the point at which w2 acts as point 2, x=35

Sum Fy=0

integral from 0 to 35 of [(w2-w1)/35in)x+w1]dx = 12000lbs


Sum M1=0

integral from 0 to 35 of x[(w2-w1)/35in)x+w1]dx - (14in)(12000lbs) = 0

I'll let you mess with the integration and solve for the two variables (or you can be crafty and replace the integrations with common shape area formulae)

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
