Question1

A 35 kg uniform ladder is leaned against a building. The 5 meter tall ladder makes an angle of 60 degrees with ground. The ladder encounters a coefficient of a static friction from ground of 0.3 and a coefficient of static friction with the wall of 0.42. A painter has to climb two-thirds of the ladder to reach a blank spot on the wall. What is utmost mass that the painter can have before the ladder begins to slip?

Question2

A wing section of L=1m and width 20m is being tested at STP conditions. The speed of air passing over the bottom surface is 290m/s as the speed distribution over the top surface can be approximated by v(x)= (vox)/L; [0,L] vo=540m/s Based on Bernoulli’s principle, conclude the lift (the net force) acting on wing. (The air flows in the x-direction.)
