A flanged bolt coupling consists of ten steel 20-mm-diameter spaced evenly around a bolt circle 300mm in diameter. Determine the torque capacity of the coupling if the allowable shearing stress in the bolts is 40 MPa. Express your answer in KN-m and use two decimal places.
Steel design, PROBLEMS 1-1 What is the steel and how can we change its properties? 1-2 What is the alloy steel? 1-3 What is the effect of increasing the percentage of carbon in steel? 1-4 Describe the process of quenching and tempering of steel. 1-5 What is the difference between anealing process and normalizing process? 1-6 What is the preferred type of steel to be used for C, L sections, plates and bars. 1-7 Which type of steel is used...
Can you help me for this Steel Design problem? I. Using Grade 50 steel, calculate the factored bending moment capacity (% Mn) for a W18x50 section. Assume Cb 1.75. The unbraced lengths are: (a) 5 ft (b) 9 ft (c) 12 ft (d) 18 ft (e) 20 ft () 30 ft
2- A welding operation will take place on carbon steel. The desired welding speed is around 0.8 in./s. If an arc welding power supply is used with a voltage of 12 V, what current is needed if the weld width is to be 0.2 in? Assume that the weld cross-section is triangular. (20 marks) 3- For question 2, what would be the temperature increase of the entire structure due to the heat input from welding only? Hint: H()DVCA(20
We say that zois a source or a sink for a given flow f(2) if there exists a circle around it such that the contour integral of f(z) around this positively oriented circle is purely imaginary with imaginary part positive or respectively negative. Alternatively, we say that zois a positive or negative vortex for a given flow if there exists a circle around it such that the contour integral of f(z) around this positively oriented circle is real positive or...
1- A rigid rod ABC is hinged at A, and supported by a steel wire at B, and a brass wire at C. The rod ABC can rotate around the hinge at A. A force L = 13(k) is applied at the mid point of the part BC of the rigid rod. The temperature of both wires connected at B, and C is reduced by 40 °C. Both wires have a length L = 4 m and a cross-sectional area...
.13 : Assume that we make an enhancement to a computer that improves some mode of execution by a factor of 10. Enhanced mode is used 50% of the time, measured as a percentage of the execution time when the enhanced mode is in use. Recall that Amdahl’s law depends on the fraction of the original, unenhanced execution time that could make use of enhanced mode. Thus, we cannot directly use this 50% measurement to compute speedup with Amdahl’s law....
