A rotating shaft is made of 42- × 4-mm AISI 1018 cold-drawn steel tubing and has a 6-mm-diameter hole drilled transversely through it. Estimate the factor of safety guard- ing against fatigue and static failures using the Gerber and Langer failure criteria for the following loading conditions: (a) The shaft is subjected to a completely reversed torque of 120 N · m in phase with a completely reversed bending moment of 150N · m. (b) The shaft is subjected to a pulsating torque fluctuating from 20 to 160 N · m and a steady bending moment of 150 N · m.

Q1: You are designing a high-pressure oxygen cylinder for hospitals fighting against COVID. The material used is layered unidirectional continuous fiber reinforced composite, as schematically shown in Fig.1 (a). In the 0° layer, the fiber is along the Y direction, and the fiber is along X direction in the 90° layer. The thickness of the 90° layer is 1.5 times of that of the 0° layer. The matrix material is an isotropic material with the Young's modulus E-10 GPa and volume fraction Vm-20%, while the continuous fiber is an anisotropic material with the Young's modulus E₁-250 GPa along the length direction, E2-20 GPa along the transverse direction and volume fraction V₁-80% a) Based on rule of mixture and mechanics of material method, calculate the effective Young's modulus along each direction (Ex, Ey, E₂). b) The as-produced (unloaded) inner radius Ro-0.1 m, the wall thickness H=0.005 m (<
basically we’re designing a machine that has rollers to flattened and rotating shaft to roll a strip of dried leaves into a bundle. Now we were advised to provide calculations with the relevant engineering parameters including the sizing of gears, belt and pulley, the torque requirement of each machine element and the power rating of the motor. The entire machine is powered by a stepper motor connected with a timing belt and pulley for power transmission. and gears that will rotate the shaft. Can you give us the flow of calculations from the rollers, the rotating shaft, up to sizing pf belt and pulley and gear ratios, with the last step as finding the power requirement (in hp) of the entire machine?
As a technologist, you are given the following design task: In a manufacturing environment, the final product needs to be packaged and sealed. After the product is placed inside the plastic bag, a hot pressing die is to be used to seal the plastic bag by application of heat and pressure. The operation should be as follow: By pressing a pushbutton switch, the heating rail is advanced and the packaging material is heated along the adhesive strip. After the adhesion pressure has been reached, the heating rail must return to its start position The design specification includes the following: Pressure dependent reversal with monitoring of the end position by means of magnetic proximity switches. Include safety measures, a green light to show when the system is ready, a red light when system is in operation, a warning sound when the heating rail is moving. 1. Draw your pneumatic circuit design for this application. 2. Draw the electric circuit diagram for your design.
According to the World Intellectual Property Organization (WIPO), Intellectual property (IP) refers to creations of the mind, such as inventions; literary and artistic works; designs; symbols, names and images used in commerce. The IP is very important for the construction industry. This is because a lot of technical innovations occur in an engineering company and protecting their knowledge of IP is necessary Examine the governing statute related to IP rights in Malaysia. Determine the common issues involving IP rights.
