1. Winds of 50 mph happen frequently around high-rise buildings. What is the total lift force that such a wind exerts on a 2'x3' glass window? What is the weight of this pane, if its width is 4 inch? The density of glass is 2.5 x 10kg/m. 2. A shingle of dimensions 8"x16" has to withstand the lift force created by winds of up to 80 miles per hour. (a) What is the total lift force (in N) created by such a wind on the shingle? (b) The shingle is held in place by two adhesive strips, each 1" wide (see figure). What is the minimal "adhesive stress" (in N/m) that the 16" Wind, 80 mph Adhesive strips strips should provide to counter the lift force? Consider the weight of the shingle as a safety factor. It does not count in the balance of the forces. 1. Winds of 50 mph happen frequently around high-rise buildings. What is the total lift force that such a wind exerts on a 2'x3' glass window?
