Problem 8. (1 point) Consider a window the shape of which is a rectangle of height h surmounted by a triangle having a height T that is 0.4 times the width w of the rectangle (as shown in the figure below). Window If the cross-sectional area is A, determine the dimensions of the window which minimize the perimeter. h= 0.9399sqrtA w 0.548sqrtA Note: You can earn partial credit on this problem preview answers Entered Answer Preview Result Messages 0.9399*sqrt(A) 0.9399/A...

A tunnel of length L = 130 m, height H = 7.3 m, and width 5.5 m (with a flat roof) is to be constructed at distance d = 47 m beneath the ground. (See the figure.) The tunnel roof is to be supported entirely by square steel columns, each with a cross-sectional area of 893 cm2. The mass of 1.0 cm3 of the ground material is 2.1 g. (a) What is the total weight of the ground material the...

2. A beam with the following cross section has to be designed to resist factored positive moment demand, Mu, equal to 1500 kip-in. Due to architectural reasons, the dimensions of the section are pre-defined as below. Also, only #8 and #9 bars can be used as longitudinal reinforcement and #4 bars as transverse reinforcement. The specified cover is 2". The compressive strength of the concrete is 4000 psi and grade 60 is used for the steel bars. The cross section...

Cross section at the wall Problem Statement: Consider a round beam of diameter d= 25 mm, length L = 10 mm, cantilevered (clamped) to the wall (as shown in the figure), loaded by P=5.5 kN. Further pay attention to points A, B, and C (half way between A and B) in the cross section at the wall, where the bending moment is maximum. Hint: The location of the centroid of half a circle can be found in Table A-18. Hint:...
