Two Camels on the opposite river banks pull a floating crate moving parallel to the bank by
means of two ropes. Assuming Equilibrium and the camels doesn't move vertically. . The
tension of these ropes are 150 kN and 250 kN, while the angle between them is 75 deg. Find
the Resultant pull on the crate and the angle between each ropes with the horizontal axis.

8. A ladder leans against a wall at an angle 0 with the wall. The
top
of the ladder is round and smooth so as to not make a mark on
the smooth wvall. The feet at the bottom of the ladder do have
friction. The ladder is uniform, of length L and weight w, and the
painter climbing the ladder has weight 10w. Assume that the
distance along the ladder that the painter can achieve before the
ladder slips is aL, where a is a number between 0 and 1. A) Show
that a = [(1.1µ/Tan(e) - 1/20]. B) In order for the painter to be
able to stand at the top of the ladder, show that Tan(e) = 1.05µ. C)
Are the answers to A) and B) minimums or maximums. BRIEFLY
explain which and why. D) How could you change the design of
the ladder to make it safer? Explain.
