please write some steps
Fig.Q3 A driving shaft is made of steel whose modulus of rigidity is 80 GN/m2. As shown in Fig.Q3(a), the shaft has a solid circular section and is subjected to a torque of 1400Nm applied, as indicated. 3. Calculate the angle of twist of one end relative to the other and the maximum shear stress which results. (a) As shown in Fig.Q3.(b), part of the shaft is then made hollow by boring a 35 mm diameter...

Problem 9.43 The 4 m x 4 m horizontal roof of an uninsulated aluminum melting furnace is comprised of a 0.08-m-thick fireclay brick refractory covered by a 5-mm-thick steel (AISI 1010) plate. The refractory surface exposed to the furnace gases is maintained at 1700 K during operation, while the outer surface of the steel is exposed to the air and walls of a large room at 25 0C. the emissivity of the steel is 0.3. (a) What is...

Q-1. You are testing a circular beam of two metals, 1045 steel and 2014-T6 aluminum, in a rotating-cantilever beam fatigue test. If you need to choose one of these metals so that you can essentially design a part made of that metal, and subject the part to a repetitive stress- amplitude without ever failing due to fatigue, which one would you choose (See the attached figure) 600 T-51-25 tanium alloy 500 00 Maximum 8 MP 300 Ductile Castro 200 700...

a 0.4 m diameter, thin walled steel pipe is used to transport
saturated steam
Problem 3.049 A 0.4-m-diameter, thin-walled steel pipe is used to transport saturated steam at a pressure of 20 bars in a room for which the air temperature is 25°C and the convection heat transfer coefficient at the outer surface of the pipe is 20 W/m2-K. (a) What is the heat loss per unit length from the bare pipe (no insulation)? (b) Estimate the heat loss per...

Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...

Aluminum rivets used in airplane construction are made slightly larger than the rivet holes and cooled by "dry ice" solid CO2 before being driven. If the diameter of a hole is 4.500 mm, what should be the diameter of a rivet at 23.0°C if its diameter is to equal that of the hole...

I need help with question 1 and 2, can anyone help me please. 1. steel wire is used to attach a balloon on a solar panel boom so that the actuators can be tested. Actuators are the devices that re used to extend the panels from their slowed position during launch to their final extended on- orbit configuration. The balloon must be filled with Helium gas such that the weight of the panels is balanced. Solar panels and their booms...
