QUIZ#1 APPLIED ELASTICITY SEPTEMBER 21, 2001 1-10. (30 points) The above cantilever beam, fixed at x=L, is loaded by a uniformly distributed load ‘q’ (units of ‘q’ are of force/length) over the length ‘L’ and a load ‘P’ (units of force) as shown. Answer the following questions (1-10) assuming plane stress. 1. One of the local boundary condition on the top surface is a. L x 0 , q ) h , x ( yy < < - = - σ b. L x 0 , b / q ) h , x ( yy < < - = - σ c. L x 0 , q ) h , x ( yy < < = - σ d. L x 0 , b / q ) h , x ( yy < < = - σ 2. One of local boundary conditions on the bottom surface is a. L x 0 , q ) h , x ( yy < < - = σ b. L x 0 ), bh 2 /( P b / q ) h , x ( yy < < + - = σ c. L x 0 , 0 ) h , x ( yy < < = σ d. L x 0 , b / q ) h , x ( yy < < = σ y x 2h b P q
