equilionum equations to the free-body diagram of either segment. Provided the structural member is homogeneous and is not irreversibly deformed, these loadings can be considered to act at the centroid of the member's cross-section. The customary sign conventions are to say the normal force is positive if it creates tension, the shear force is positive if it causes the beam segment to rotate clockwise, and a bending moment is positive if it causes the beam to bend concave upward. Oppositely-acting loadings are considered negative. Figure B 30⁰ d <4 of 4 ▼ Part B-Internal Loading on a Semicircular Member Consider the semicircular member and loading shown in the image where d-0.830 m and F = 65.0 N.

I tried doing this one and I just dont know how else I could have calculated the answer could you help me out with how this problem is sapposed to be worked?

1. For the rigid bodies shown in Figures 1-5, draw free body diagrams. Smooth surface A Figure 1: Figure 2: -P Sharp corner B

The simply supported beam is subjected to the loads as described in the figure and parameter table. Neglecting the thickness of the beam, calculate the horizontal and vertical support reactions at A. F, F2 parameter value units L L2 L3 1.75 ft 1.5 ft 2 ft 30 70 F1 F2 lb 6 lb For the answers, take to the right, up, and counterclockwise to be the positive directions. The horizontal support reaction is lb The vertical support reaction is lb The moment support reaction is lb-ft

Two forces are applied to a flywheel 50 cm in diameter. Each force is 500 N. The shaft is fixed to the wall using three grade 5 steel bolts. The distance between the bolts and the axis of rotation is 10 cm.    (a) What moment of resistance must develop the three bolts together    Answer: 250 Nm    (b) What is the resistance force F of each bolt?   Answer: 833.3 N    (c) What is the diameter of the bolts if their factor of safety is 10?    Answer: 4.14mm

The state of stress at a point in an engine piston is given in the x-y-z coordinates by: 90 180 [0]=0, MPa = 180 240 yx yy 120 zy Using the matrix transformation law, determine the state of stress at the same point for an element rotated about the x-axis (in the y-z plane) 60° clockwise from its original position. Calculate the stress invariants and write the characteristic equation for the original state of stress, Calculate the deviatoric invariants for the original state of stress, Calculate the principal stresses and the absolute maximum shear stress at the point. What are the stress invariants and the characteristic equation for the transformed state of stress, а. b. С. d. e

Pressure vessels are very common in many industries. The purpose of this exercise is to examine how stresses evolve within the walls of a pressure vessel as a function of position within the wall and wall thickness. Recall the thick-walled cylinder solution developed in class. Re-write the solution to the case of a thick-walled cylinder with inner radius a, outer radius b, internal pressure p₁, and external pressure, p2. Orr = 000 = + a²p₁-b²p2 (P2₂ - P₁)a²b² 1 (b²-a²) (6²-a²) ²¹ a²p₁b²p2 (b²-a²) 1 axis (P2 - P₁)a²b² 1 (b²-a²) r² (a) Draw a diagram showing the evolution of orr and σ00 from a to b when a/b=0.5 and P2 = 0. (b) Make the assumption that p₂ = 0, a + b ≈ 2r, ba≈t, and a b≈r to derive the expression for orr and one for a thin-walled pressure vessel. For a sanity check, your solution should be arr 0 and σ00 = pir/t. = (c) Now consider the classical strength of materials approach to pressure vessels. Imagine the pressure vessel shown in Fig. 2 (note, the radius of the…
