Quiz: A straight beam ABCD is rigidly built-in at A and D and carries point loads of § kN at B and C. AB = BC =CD = 1 8m If the second moment of area of the section is 7 x 10‘m* and Young’s modulus is 210GN/m’, calculate: () The end moments; (b) The central deflection of the beam.

please answer do not image format

Assume EI constant. For the beam below determine: A) The slope at point ? B) The displacement at the end point A Solve the problem using the 1) Conjugate-Beam Method and 2) Moment-Area Theorem. Please show all steps used as I am confused.

Calculate the support reactions at A and B for the loaded beam.Assume P = 58 lb, w = 105 lb/ft, a = 2.7 ft, and b = 5.5 ft.

Beam shown below, (a) calculate the reactions at A and B, and (b) calculated the shear long the beam. L

A beam, which is fixed at one end, is acted upon by a distributed load (the curve is a continuous cubic curve) as shown in the figure. Calculate the reactions at the support. Include proper signs (with right, up and counterclockwise assumed to be positive for X, Y and the moment) 300 N/m y = kx3 %3D 300 N/m 4 m 3 m Ry (in N) = ? R,(in N) = ? M* (in N) =?
