A spherical furnace has an inside diameter of 6ft and an outside diameter of 8ft. The furnace shell is made of two different materials, each 6inches thick. The inner and outer section of the shell has a thermal conductivity of 0.10 BTU/hr-ft- °F and 0.2 BTU/hr-ft- °F, respectively. The inside temperature is 2, 500 °F, while the outside surface is at 150°F. Calculate the heat loss for 24 hours of operation. Express your answer in scientific notation. 1= 3ft r2= 4ft r3= 4.5ft r2= 5ft A= inner section B= outer section KA= 0.1 BTU/hr-ft- °F kB= 0.2 BTU/hr-ft- °F T1= 2500 °F T4= 150 °F

hi ive have nearly completed this model but i am stuck on a couple last parts. Firstly, the holes on the top need to be placed 30 degrees from the y axis as shown in the handout but also the middle part is meant to have triangular "supports" rather than rectangular and im not sure how to cut them down. This is in autodesk inventor but any help here would be appreciated Once again just the top holes being moved 30 degrees and the support being cut down to the triangular shape shown in the handout
An engineer is creating a solid model of a simple gear using SolidWorks. Choose the correct statement below. The only way to generate multiple gear teeth is to sketch each tooth individually and then extrude each tooth individually. The engineer can use the linear pattern tool to create an array of gear teeth in a circular pattern about the center of the gear from a sketch of a single tooth. The engineer can use the circular pattern tool to create an array of gear teeth in a circular pattern about the center of the gear from a sketch of a single tooth. It is not possible to model gear teeth in SOLIDWORKS due to the complex shape.

[Problem]A scene-of-the-crime-operative is called to investigate a dead body that has just been found. She arrives on the scene at 9:23 pm and begins her investigation. Immediately, the temperature of the body is taken and is found to be 27.76°C. The detective checks the programmable thermostat and finds that the room has been kept at a constant 20°C for the past 5 days. After evidence from the crime scene is collected, the temperature of the body is taken once more and found to be 25.85°C. This last temperature reading was taken exactly 2 hours after the first one. The next day the detective is asked by another investigator, “What time did our victim die?” Assume that the…
A robot is used for loading and unloading of parts to automated flexible machines. Loading time is 1 minute; unloading time is 1.5 minutes; machining time 15 minutes; Robot travel time between the machines including the inspection time is 3 minutes. Cost of robot C,=30 TL/Hour; cost of machines C2=40 TL/Hour. How many machines (integer number) should be assigned to the robot so that the total robot and machine costs per cycle are minimized? 8 - 176 a) 4 b) 3 c) 2 d) e) 6.
A flow shop consists of 3-Machines on which 4-Jobs have to be scheduled in a fixed sequence. The process times of the four jobs are given in the table below. In this table Pij, P2j and p3j indicate the process time of the jth job on Machine-1, Machine-2 and Machine-3 respectively. Work out a near-optimum schedule of processing the jobs for heuristically minimizing the Makespan using Palmer's Method. Job (j) J1 J2 J3 J4 4 8 4 2 2i P3j 4 Calculate the following: (i) The Minimum and the Maximum Processing Times on the 3-machine and hence conclude whether the machines satisfy the Johnson's criteria for 3- machines. (ii) (ii) Calculate the Directed Graph and Gant Chart; Hence calculate the value of Makespan, Cmax. (iv) Calculate the slope-index and hence decide the heuristic schedule; SO53 5M56

1) During a particular manufacturing process a hoop of mass m and radius r is to roll without slip on a slant before getting to the next step in the assembly line. The floor manager has approached you and wants to know what the minimum coefficient of friction would have to be to prevent the hoop from slipping. a) Explicitly define coordinates for the inclined plane and write out the corresponding transformation array. b) Draw an FBD and IRD for the system. c) Compute the coefficient of friction required to ensure the hoop does not slip if B = 45°.
