The shaft is made of A992 steel with the allowable shear stress of 𝜏allow= 75 𝑀𝑃𝑎. If gear B supplies 15 kW of power, while gears A, C and D withdraw 6 kW, 4 kW and 5 kW, respectively. Determine the required minimum diameter 𝒅 of the shaft to the nearest millimeter. Also, find the corresponding angle of twist of gear A relative to gear D. The shaft is rotating at 600 rpm

The paint-spraying robot is programmed to paint a production line of curved surfaces A (seen on edge). The length of the telescoping arm is controlled according to b = 0.3 sin (πt/2), where b is in meters and t is in seconds. Simultaneously, the arm is programmed to rotate according to 0 = π/4 + (π/8) sin (πt/2) radians. Calculate the magnitude v of the velocity of the nozzle N and the magnitude a of the acceleration of N for 1 = 1 s and for 1 = 2 s.

Question
A three-story building has interior columns spaced 8m apart in design loads for the building are as follows: DL: 5.0 kPa (Roof) 7.0 kPa (typical for each floor) LL: 0 (Roof Deck) 6.0 kPa (2nd Floor) 2.4 kPa (3rd Floor) Recognizing that the probability of supporting a large fully loaded tributary area is small, building codes permit reduction. Use the attached alternate floor live load reduction provisions. What is the total axial load on an interior column at the ground floor level due to service LL?
