Learning Goal: To determine the support reactions in a statically indeterminate beam using the moment- area method. Part A - Support reaction force at B The beam shown has length L = 15.0 ft and is loaded with the applied moment M = 210 kip - ft at B. Assume EI is constant. (Figure 1) Using the moment-area method, determine the magnitude of the unknown support reaction at B due to the applied moment. Express your answer to three significant figures and include appropriate units. > View Available Hint(s) ? |By| = |10.5 kip Submit Previous Answers

A rigid beam of length 490 cm and uniform mass 89 kg suspends two masses on light strings at each end as shown in the figure. If mass m₁ = 33 kg and m₂ = 49 kg, at what distance x should the pivot be placed such that the beam is balanced? X m1 Lütfen birini seçin: a.149.59 cm b.232.18 cm c.206.14 cm d.345.14 cm e.267.92 cm pivot m2

Learning Goal: To determine an I-beam's maximum bending moment, moment of inertia using the parallel-axis theorem, and the maximum stress at a given location using the flexure formula. As shown, I-beam ABC supports a sign that weighs S = 30 lb . The I-beam is 24 in. long and is further supported by a rod that is attached 18 in. from the wall. Assume that all forces acting on the I-beam act along its centroid and that the I-beam's weight is negligible. Let the dimensions of the I-beam be w = 4 in., g = 0.8 in., h = 2.9 in., j = 1 in., c = 6 in. c A ·a b B Part A - Free-body diagram of beam ABC S C H j- W h Before the problem can be analyzed, a free-body diagram must be drawn to understand the forces and reactions that act on the I-beam. Draw the free-body diagram of beam ABC. A free-body diagram includes the forces acting on the object, in this case the beam. Start your vectors at the black dots. You will not be graded on vector length. Ignore all reaction forces in the x direction, and…

b. find the second moment of area of a cross section OC. find the centroid of a cross section O d. none of these options If the "I" value of beam cross section is 6,400,000 mm and the maximum distance from the neutral axis of the cross section to the top and bottom edges of the beam cross section is 129 mm, what is the section modulus of the beam? Note: Give your answer in mm³ Note: Do NOT include units in your answer. Answer: X A typical value for the stiffness of aluminium alloy is... Select one: a. 200 GPa b. 72 GPa
