Calculate non-zero stress components (normal and shear) at points A, B and C. Point C is located at the center of the cross section attached to the wall. Calculate non-zero strain components at point B. Neglect shear stress due to shear force. Given: loading F = 400 N, P-2000 N, and T = 75 N·m, Young's modulus E = 70 GPa, Poisson's ratio v = 0.25 15-mm D. -100 mm

16 mm 16 mm A M B |--40 mm-|--40 mm-| B D Couple-moment M is applied to the beam, which has a cross-section, as shown in the Figure. if M = 458 Nm and ß =62 Determine the stresses at points A, B and D. Also determine the orientation of neutral axis measured from z-axis.

Please help me answer this asap thank you

A compression load of P = 55 kips is applied to a 2 in. by 2 in. square post, as shown. Determine the normal stress σn perpendicular to plane AB and the shear stress τn⁢t parallel to plane AB. Assume α= 30°.Calculate the normal force N perpendicular to the plane AB and the shear force V parallel to plane AB. Report both answers as positive numbers.Answers: N =    kips, V =    kips.

A thin triangular plate PQR forms a right angle at point Q. During deformation, point Q moves to the left by u = 1.7 mm and upward by v = 3.5 mm to new position Q'. Determine the shear strain y at corner Q' after deformation. Use c = 720 mm, a = 31% and 3 = 59° Answer: y = i P R urad

A thin triangular plate PQR forms a right angle at point Q. During deformation, point Q moves to the left by u = 2.6 mm and upward by v = 5.2 mm to new position Q'. Determine the shear strain y at corner Q' after deformation. Use c = 620 mm, a = 29°, and B = 61°. 41 Answer: y = i urad

Athin rectangular polymer plate PQRS of width b = 429 mm and height a = 140 mm is shown in the figure. The plate is deformed so that corner Q is displaced upward by c = 1.6 mm and corner R is displaced leftward by the same amount. Determine the shear strain at corner P after deformation. a Y = y i b Q S a X urad
