A shear force, S₂ is applied. This results in shear flow, shown with red arrows, which has the following values:
• Shear flow in part 13, just before point 3 - 38 N/mm
Shear flow in part 23, just before point 3 = 44 N/mm
Shear flow in part 43, just before point 3- 44 N/mm
What is the shear stress in part 35, just below point 3?
Express your answer in MPa, to 2 decimal places but without the units included. You have a 3% margin of error.
use the given information to answer the question.
the horsepower (hp) that a shaft can safely transmit varies jointly with its speed (in revolutions per minute (rpm)) and the cube of the diameter. if the shaft of a certain material 3 inches in diameter can transmit 45 hp at 110 rpm, what must the diameter,d, be in order to transmit 65 hp at 150 rpm? (round your answer to two decimal places.)
d= inches
p1= 1780 N
p2 = 1570 N
p3 = 1340 N
