1. Determine stress distributions of a rotating ring (See the figure below; Angular speed: 0; Mass density: p). a b

A steel wire 10 m long, hanging vertically supports a tensile load of 2 KN. Neglecting the weight of wire, determine the required diameter if the stress is not to exceed 140 Mpa and the total elongation is not to exceed 5 mm. Assume E = 200 Gpa. A. 2 mm B. 3 mm C. 4 mm D. 5 mm Please solve the Problem elaborately and Refer Machine Elements and Stresses Equations from the figures or use other shortcut Methods you have or you may Solve both or in more different methods the better ?. Your solution will be use as reference for my Future Board Exam preparation/review/study. Thank you so much dear your work will be appreciated much and rated excellently.

Q5: Draw the Mohr's Circle of the stress element shown in figure. Find: - The stresses acting on inclined plane A-B with Y -axis. A 60 6 MPa B 6 MPa 6 MPa

A circular bracket with a diameter of 100 mm is fixed to a wall as shown in the figure below. Determine and draw the state of stresses in small infinitesimal cubic elements located at points M and N on the cross section A.

A thick-walled cylinder with closed ends has internal and external radii 100 mm and 180 mm respectively, is subject to internal and external pressures of 148 MPa and 58 MPa respectively. Apply Lame's equations to find the following: Radial and hoop stresses at radii 120 mm, 140 mm and 160 mm respectively. (a) (b) Axial stress of the cylinder.

The pinned members shown in figure carry the loads P and 2P. All bars have cross-sectional area A. Determine the stresses in bars AB and AF. L G B 2P 2L

For the beam shown in the figure: Determine the normal and shear stress at a point located at 4.5 ft from support B and 4 inches from the top of the section. Draw the Mohr's circle for the stresses at that point and calculate the principal stresses and the max in plane shear stress as well as their directions. Show these stresses on appropriately oriented elements. A 1600 lb 1.5 ft 80 lb/ft -9 ft B 1.5 in. 4 in 11.5 in.

3. A rectangular solid bar of width 20mm and depth 35mm is subject to a pure positive moment of 450Nm. Calculate the stress in the bar and sketch the stress distribution through its thickness along the centre line. 4. The bar in Q3 is also subject to a tensile load of 15kN applied at the centroid of area. Calculate the stress in the bar and sketch the stress distribution through its thickness along the centre line.
