Leaning pole
A pole of negligible mass leans against a wall, at angle ? with the horizontal. Gravity is directed down
(a) Find the constraint relating the vertical acceleration of one end to the horizontal acceleration of the other.
(b) Now suppose that each end carries a pivoted mass M. Find the initial vertical and horizontal components of acceleration as the pole just begins to slide on the frictionless wall and floor. Assume that at the beginning of the motion the forces exerted by the rod are along the line of the rod. (As the motion progresses, the system rotates and the rod exerts sidewise forces.)

If the flexural modulus is 6.9 GPa, determine the minimum distance between the supports. Will the polymer fracture if its flexural strength is 85 MPa? Assume that no plastic deformation occurs.
For a one-dimensional wall (a slab) with a thickness of 60 mm and a thermal conductivity of 27 W/mK, the temperature distribution is given by T(x) = a + bx + cx^2 where a = 300 C, b = 160 C/m, and c = -2000 C/m^2. The x is in meters. Determine the in..
