O Its moment is cancelled out when summing moments in the system to establish embedment depth "d". O Is divided by the factor of safety z 1 in the analysis of anchor wall Is multiplied by the factor of safety ≥ 1 in the analysis of anchor wall

To (a) Find the forsional stiffness of the chanel section Shown, Polov (STIDEES ridots WON (6) consider a structure for which +₁ = 3/4 inch, t₁ = 1/2 inch, 6=4 inches, a = 6 inches and G = 3X107 psi. Determine the angle of twist per unit length when the structure is subjected to a torave of 25,000 1b-ins. C) If the total length of the structure of Part (b) is 6ft, and the shaft is fixes at one end, determine the maximum angle of twist. What is the angle of twist at half-span?

A cross-section is subjected to a maximum shear of V=160 kN (see figure): Determine the centroid of the cross-section. Calculate the moment of inertia (I) of the cross-section. Determine the shear stress at point A in the cross-section.

QUESTION 1) The cross sectional Е, A, Е, А, areas of the KM and MR intervals are A1 = 400 mm? and A2 respectively. Both sections are made = 200 mm², from the same material that has elastic L. M N R K modulus ofE = 200 GPa. If the gap in figure is 8-5mm and the axial forces are Pi = 120 kN and P2 1m 2m 2m 1m = 80 kN; a) Calculate the support reactions. b) Draw the axial force diagram.
