A long (into the page) duct with three walls is shown in the figure below. A constant rate
of energy (q = 5000 W) is supplied to the backside of the bottom wall. All this power leaves
surface 1 as radiative heat flow into the duct (i.e., participates in radiative exchange with
surfaces 2 and 3). The backside of Surface 2 is perfectly insulated. The table below lists
geometric and radiative properties of each surface.

The power transmission system shown in the figure includes a helical and a bevel gear. The shaft is supported by two bearings and rotates at 600 rpm. The load on the bevel gear is -0.5Pi - 0.41Pj + 0.44Pk. The axial load on the shaft is carried by the bearing on the left. For a lifespan of 36,000 hours and 98% reliability, select two identical single-row tapered roller bearings.

- As shown in the figure, a shaft manufactured with a surface treatment will carry the belt-pulley system, which is loaded with continuous and non-impact loads (in the YZ plane at α = 30 degrees). Design a shaft with a 95% reliability rating, a 2.5 safety factor, and made of cold-drawn AISI 1045 material. The shaft has no discontinuities or radius.arrow_forwardAir is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 12, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K. The properties of air at room temperature are cp=1.005 kJ/kg⋅K and k=1.4 . Determine the required mass flow rate of air for a net power output of 66 MW, assuming both the compressor and the turbine have an isentropic efficiency of 85 percent.

The figure shows a worm shaft carrying a 52 kN eccentric load. The shaft is supported by bearings that carry radial and axial loads. The load is suspended from the nut, as shown, preventing rotation. The torque applied to overcome friction and lift the load is 450 Nm. Calculate the stresses at points A and B. Knowing that the shaft is made of AISI 4140 alloy steel tempered at 540˚C, determine whether it is safe according to the maximum shear stress theory. 400 mmarrow_forward
