The state of stresses at a given point in a material is shown in the figure below together with possible Mohr circle diagrams corresponding to this state of stress. Which of the following circles is correct? 20 N/mm? 10 N/mm2 40 N/mm2 40 N/mm? 10 N/mm2 20 N/mm? 10 20 40 to to 10 -10+ 10 -10+

Hi, i was wonderwing why with the normal stress at B the moment Mx * Cy is minus. can you explain how to set up the correct equation for the normal stress. Because often i had a correct answer but the minus and pluses different.

2. Given the following state of stress 011 = -2x? 012 = -7 + 4x1x2 + X3 013 = 1+ x1 - 3x2 022 = 3x? – 2x3 + 5x3 023 = 0 033 = -5 + 3x2 + 3x3 + x1 Determine the body force components for which the stress field describes a state of equilibrium.

The state of stresses in the x and y directions at a point in a given material is shown in the figure below. If the value of the shear stress in the x-y axes Ty is 11 N/mm², find the minimum direct stress that can be found at this point in any possible direction. Round off your answer to the nearest N/mm?. If the answer is negative do insert the "-" sign. 10 N/mm2 Txy 20 N/mm2 20 N/mm2 Ixy 10 N/mm2

I need right solution with clear calculations

Computation must be completeAnswer in two decimal places.Box your final answer

A steel rod with a cross sectional area of 180 mm² is stretched between two fixed points. The Tensile load at 25 degrees is 3600 N. Assume α= 11.7 x10^-6 mm/(mm –degree celsius) and E = 200 GPA. Calculate the temperature at which the stress will be zero. Your answer

Two solid cylindrical rods 1 and 2 are joined together at metal plate B loaded. If the normal stress in each rod is limited to 40 ksi, determine the minimum diameter for each rod (in inches). Note: Draw the Free Body Diagram, include the units/dimensions, use the proper formula and round-off all the answers and final answers to 3 decimal places.

Please explain with full detail step by step so I can understand, the answer should be 1800 ksi
