CLO 2: The girder of a simple log bridge supports a wheel load W acting at any position along the span. In addition, the weight of one log and the planks it supports is equivalent to a uniform load of 850 N/m acting on the log. If the cross section of the beam is a square whose area is the same as that of the 300mm circular section, determine the maximum permissible wheel load W (in kN) based upon an allowable bending stress of 2 MPa. 850 N/m 300 mm -2.5 m O 77.4 28.9 8.96 O 38.7

A timber beam has a rectangular cross section, 150 mm wide by 300 mm deep, and is simply supported over a span of 4 m. The beam is subjected to a two-point loading at the quarter span points. If the beam fails in shear when the total of the two concentrated loads is 180 kN, determine the maximum shear stress at failure. Ans. 3 N/mm?.

A uniform T-section beam is 100 mm wide and 150 mm deep with a flange thickness of 25 mm and a web thickness of 12 mm. If the limiting bending stresses for the material of the beam are 80 MN/m2 in compression and 160 MN/m2 in tension, compute the second moment of area. 110.4 mm   111.4 mm   109.4 mm   108.4 mm

A safety engineer establishing limits on the loads that can be carried by a forklift analyzes the situation shown. The dimensions are a = 32 in, b = 30 in, and c = 26 in. The combined weight of the forklift and operator is WF = 1281 lb . As the weight WL supported by the forklift increases, the normal force exerted on the floor by the rear wheels at B decreases. The forklift is on the verge of tipping forward when the normal force at B is zero. Figure 69€ W₁ W B E 1 of 1 Ơ Part A Determine the value of W₁, that will cause this condition.

Subject: Reinforced concrete Design- Civil Engineering   A rectangular beam reinforced for tension has b = 300mm, d = 480mm. The beam is reinforced with 7 of 25mm bars with fc' = 21MPa and fy = 415MPa. If the beam is cantilever, 3m long and supports a uniform dead load of 15kN/m (including its own weight) applied along its entire length, the maximum value of the concentrated live load that can be applied 2m from the free end is kn.   Choices: A. 141kN B. 114KN C. 213kN D. 231kN
