Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…

Transfer time between stations is 30 sec. total time required to setup the entire line is 102 hr. Assume that the operation times at the individual machines remain the same as in the previous problem, Determine (a) manufacturing lead time for a part coming off the line,…

A batch of 35 parts is ordered by a customer about every six months. The parts are currently processed sequentially through five conventional machines, listed in the following table with setup times and work cycle times per piece. These machines all require an operator to be in attendance during the work cycle. There is a delay of 10 hr/machine dueto transport between machines and waiting in queues of other parts processed by thesemachines. A recommendation has been made to process the parts on a new multitaskingmachine that would complete the batch in one setup, which would involve a simple fixtureand a setup time of 2.0 hr. The work cycle on the multitasking machine consists of thesame operations that are accomplished by the five machines, but the cycle time would beless than the sum of the five cycle times by one-half because of tool path improvementsand reduced part handling. Determine the manufacturing lead time (how long it takes tocomplete the batch of 35 parts, including…

Problem: Consider fully-developed flow of water through a 24-cm diameter tube. The water comes in at 20°C and exits at 40°C. The surface temperature of the tube is uniform at 60°C. The water flow has a mass flow rate of 0.24 kg/s. What is the average convection coefficient of the water flow? Solution: We have T, = 60°C, Tmi = 20°C, Tmo = 40°C, So, the bulk-mean temperature is Tm = 30°C. The appropriate properties are: u = 7.98 × 10-4 kg/ms; k = 0.615…

Answer the two connected questions (Task A-1 and A-2). Provided in the last part are the guides and examples: The process for large-scale manufacture of paper has been largely unchanged for the last 125 years. The pulp and paper industry today is highly capital intensive, and there is an ongoing drive towards process integration, thereby increasing the efficiency of utilization of available process resources. This paper deals with the Kraft process (see Fig. 1) though the general principles described can be extended to other pulping processes. As shown in Figure 1, five water sinks and four water sources are considered for in-plant water reuse/ recycle. Prior to water reuse/ recycle, the network requires a freshwater flow rate of 36,400 tonne/day and generates 37,186 tonne/day of wastewater (sum of the individual sink and source flow rates in Table 1). The freshwater source that is available for service has an impurity concentration (chloride content) of 4.2 ppm, which is higher than…

1. You are a mechanical engineer at one of the oil and gas company and you face this technical problem inside plant: a broken chain issue that frequently occured on a machine lately. Obviously this issue causes production activity stopped temporarily and production loss.This broken chain issue occured since about three months ago after we replaced the electric motor into the bigger one, it's about 2.2 KW or 3 hp. As an engineer in this department, You responsible to stop this broken chain happened on and on. So, make a calculation to find out the optimum specification of chain sprocket thru theoritical approach based on Machine Design. Motor Power (P) = 3HP 2.2 KW = 2337 Nm/s ni = 952 Rpm : speed of rotation od smaller spracket in rpm n2 = 600 Rpm : speed of rotation od larger spracket in rpm N1 = 17: Number of teeth on the smaller sprocket N2 = 27 : Number of teeth on the larger sprocket D1 = 44 mm : Ptich circle diameter of the small sprocket D2 = 74 mm : Ptich circle diameter of the…

In the course of production, there was a major breakdown which led to a long downtime resulting in missing out on the deadline. Kasapreku had lost a great deal of money due to the company’s inability to seriously inculcate safety and maintenance engineering in their system. (a) Discuss the importance of safety in an engineering maintenance from Kasapreku’s case scenario

A company uses various machines in the preparation of ice cream. The firm has been successful until recently when it noticed growing repair expenses for the various machines it uses. Over the past 20 months, the machines have broken down at the rate indicated in the following table:   Each time a machine breaksdown, the company estimates that it loses an average of US$300 in production time and service expenses. Should the company opt to purchase a service contract for preventive maintenance by Angeles Machineries Inc., (AMI) there will still be breakdowns, averaging one breakdown per month. The price for this service by AMI is US$150 per month.   a. If the company continues as is, what is the expected no. of breakdowns based on past history? b. What will be the cost of breakdowns per month to the company without a preventive maintenance contract? c. What will be the cost of breakdowns per month to the company with a preventive maintenance contract? d. Should they engage the…

True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.
