A carpenter is preparing to put a roof on a garage that is 20 feet by 40 feet by 20 feet. A steel support beam h=41 feet in length is positioned in the center of the garage. To support the roof, another beam will be attached to the top of the center beam (see the figure). At what angle of elevation is the new beam? In other words, what is the pitch of the roof?

A steel I-beam with a span of 20 feet will support both a concentrated load of 15 kips at the beam center and a uniformly distributed load of 2 kips/ft along the entire beam length. The steel beam is Grade 50 (Fy= 50,000 psi). i) Calculate for the lightest W-shape section that will safely carry the load, with the depth not to exceed 17 inches. Provide sketches. ii) The analysis is to include (a) bending strength, (b) shear strength, and...
A mischievous SUOC student has climbed on the roof of a snow-covered building and is trying to hit her friend with snowballs as he walks through the Quad. She throws them at an angle of 20◦ above the horizontal at a speed of v0 = 5 m/s. The building has a height h = 6 m. He decides to throw a snowball back at her. He’s standing a distance d from the side of the building, and throws a snowball...

How do I solve this? Problem 2(50 points) The roof of the Edwin A. Stevens building is to be redesigned to accommodate a billboard for Stevens Institute of Technology. The new billboard will weigh 40 kips and be supported equally by two columns located 9 ft from the rear of the building. The beams supporting the new roof will be simply supported as shown. (Note there is a 5 ft overhang at the front of the building). For the grade...

Problem 3. Assume that the house is 9 feet tall, has pipe size of 20 in. and post height is 40 ft. See the chart below for the cross-sectional properties of your pipe. Assume a wind pressure of 30 psf. a. Calculate the force/foot of pipe by multiplying the wind pressure by the diameter of the pipe. The uniform load is 1200 on the pipe in lb/ft. b. Calculate the resultant force caused by the wind on the house. Treat...
Remove the rays from the simulation by clicking on them and then pressing Delete. Place a Point Source at (60,180) by clicking Point Source under Tools, then clicking the simulation at (60,180). Note that the location at which the rays converge is the same as it was using the principal ray method. This is, in fact, why we use the principal ray method: it generates the convergence point using comparatively few lines. As we know from Huygens's principal, every point...
The professor didn't make an answer key for this study guide and I wanted to know if I'm doing these right. 4. A man pushes with a force of 700 N on a broken down car at an angle of 0 degrees from horizontal. He manages to move it form to a garage. How much energy does he use? 5. A block sits on a horizontal surface with friction. The mass of the block is kg. A force of 14Nis...
Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
