Rework given Problem assuming that the beam is placed with the 100 mm dimension oriented vertically.
ProblemA timber beam is subjected to a maximum bending moment of 2600 N⋅m. The cross section of the beam is 100 mm by 150 mm. The 150 mm side is oriented vertically.
(a) Calculate the maximum bending stress.
(b) Calculate the bending stress 25 mm below the top surface.
It is required to design a low-voltage, high-current, shunt-excited DC motor for hoisting drive in industrial overhead crane system. The output power of the machine is expected to be between (20+X) hp. The copper losses in the machine should be be..
