A square post which is made up of two parts is glued at plane abcd with the angle α = 30° with the vertical. Allowable compressive stress @ glue = 5.2 MPa Allowable shearing stress = 3.5 MPa P = 36 kN. What is the minimum post dimension, w (mm), without exceeding the allowable shearing stress at the glue?

Please show all steps

Given the following properties of beam: b = 250 mm, d = 325 mm and h = 400 mm. a) Assuming the concrete is uncracked, compute the bending stresses (in MPa) in the extreme fibers of the beam at M = 100 kN-m. Blank 1 b) Determine the cracking moment (in kNm) for the section if f'c = 28 MPa. Blank 2 c) Compute the flexural stresses in the concrete and steel of the beam using the transformed-area method at M = 100 kN-m, n = 9 and reinforced with 5-16 mm diameter tension bars. Unit must be in MPa. fc = _Blank 3, fs =__________ Blank 4

2. Per ACI318-19, choose the correct value of the strength reduction factor ø for the flexural capacity of a beam with ɛ = tension face. 0.0032, where & is the strain for steel reinforcement closest to the (A)0.9 (B) 0.85 (C) 0.75 (D)0.65
