Analysis of mohr’s circle for an element oriented at an angle

using the mohr’s circle constructed for the given state of plane stress, draw the radial line which corresponds to a state of stress associated with the x plane on an element oriented 30? counterclockwise from the original position.

draw the radial line which corresponds to the state of stress on an element oriented 30? counterclockwise from the original position.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
