A rigid beam ABCD is supported by a pin at B and two cables located at A and C. The cables have a 30 mm diameter and are made of steel with yield strength of 800 MPa and elastic modulus of 200 GPa. The beam is designed to resist a vertical load P applied at D equal to 200 kN. a) Find the forces developed in each cable b) Find the corresponding vertical displacement at point where the load is...
Mainly need help with part (b) please. A rigid bar ABCD is suspended from the ceiling by two initially unstressed rods BHE and CF as shown in the figure. The rigid bar ABCD is in the position shown in the figure without any force applied and at an initial temperature of 25°C. Neglect the weight of all the members. 70 cm i 80 cm . 1 15 cm 20 cm 110 cm F- 8 kN Given: 1, Young's modulus of...
A rigid beam BCD is supported on a roller support at C (4m from B) and has two bars AB and DE attached at each end. The bars can carry either tension or compressive forces. The rigid beam carries a UDL of I kN/m across BC and a point load of P at D as shown in the figure above. The length of the two bars is 3000 mm. The elastic modulus of both bars is 200 GPa and the...
blem 5 (25 points): Consider the system of bars shown below. Bars AB, CD, and EF are connected d link BED. Determine the horizontal displacement of point F B by a rigid . Bar AB has a cross-sectional area of 0.012 m2, a Young's modulus of 200 GPa, and a length of 0.34 m. . Bar CD has a cross-sectional area of 0.010 m2, a Young's modulus of 200 GPa, and a length of 034 m . Bar EF has...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
6) 2.5-16 2.5-16 A rigid bar ABCD is pinned at end A and supported by two cables at points Band C (see figure). The cable at B has a nominal diameter dg - 12 mm and the cable at Chas a nominal diameter dc = 20 mm. A load Pacts at end D of the bar. What is the allowable load P if the temperature rises by 60°C and each cable is required to have a factor of safety of...
