Q. Consider a prismatic straight beam of length ๐ฟ = ๐œ‹ m, pinned at the two ends as shown in the figure. The beam has a square cross-section of side p = 6 mm. The Youngโ€™s modulus E = 200 GPa, and the coefficient of thermal expansion ๐›ผ = 3 ร— 10โˆ’6 Kโˆ’1. The minimum temperature rise required to cause ...

Consider an elastic straight beam of length ๐ฟ = 10 ๐œ‹ m with square cross-section of side a = 5 mm and Youngโ€™s modulus E = 200 GPa

Q. Consider an elastic straight beam of length ๐ฟ = 10 ๐œ‹ m, with square cross-section of side a = 5 mm, and Youngโ€™s modulus E = 200 GPa. This straight beam was bent in such a way that the two ends meet, to form a circle of mean radius R. Assuming that Euler-Bernoulli beam theory is applicable to ...

In orthogonal turning of a cylindrical tube of wall thickness 5 mm, the axial and the tangential cutting forces were measured as 1259 N and 1601 N, respectively

Q. In orthogonal turning of a cylindrical tube of wall thickness 5 mm, the axial and the tangential cutting forces were measured as 1259 N and 1601 N, respectively. The measured chip thickness after machining was found to be 0.3 mm. The rake angle was 10ยฐ and the axial feed was 100 mm/min. The ...

A gas is heated in a duct as it flows over a resistance heater. Consider a 101 kW electric heating system. The gas enters the heating section of the duct at 100 kPa and 27 ยบC with a volume flow rate

Q. A gas is heated in a duct as it flows over a resistance heater. Consider a 101 kW electric heating system. The gas enters the heating section of the duct at 100 kPa and 27 ยบC with a volume flow rate of 15 m3/s. If heat is lost from the gas in the duct to the surroundings at a rate of 51 kW, the ...

Q. The wall of a constant diameter pipe of length 1 m is heated uniformly with flux ๐‘žโ€ by wrapping a heater coil around it. The flow at the inlet to the pipe is hydrodynamically fully developed. The fluid is incompressible and the flow is assumed to be laminar and steady all through the pipe. The ...
