2. A spherical medium of radius R, and constant thermal conductivity ky generates heat at the rate 9 = 4.1 60(1-3) R where q, is the rate of internal energy generation per unit volume at the center and is a given constant. This medium is surrounded by a spherical shell of cladding with a thickness of R2 - R, and a constant thermal conductivity of kn. The contact resistance per area between the the cladding and the spherical medium can be taken as RC. The fluid outside the cladding is at Twith a constant heat transfer coefficient h. a) Determine the outer surface temperature of the cladding, b) Determine the temperatures of the sphere and the cladding at the interface between the two. c) Determine the temperature distribution in the sphere and the cladding.

You are working as 'Blasting Engineer' for an opencast coal mine situated in the forest which is being worked with 15 m benches employing Electric rope shovels of 10 m³ for the removal of overburden mainly consists of sandstone. The anticipating conditions are of dry rock in the upper portions of overburden and wet conditions in lower portions of geologically disturbed overburden. Design the following blast parameters with neat sketches:

1. Burden
2. Spacing
3. Stemming
4. Sub-drilling
5. Charge factor (kg/m³)
6. Explosives and initiation system
7. Decking, if any
8. Initiation sequence and pattern. Assume the other necessary conditions.

2. The sprockets of the chain drive shown at the right have diameters of 10.0 cm and 20.0 cm. The small sprocket reaches a rotational speed of 100 rpm in 7.00 s. a) Calculate the required angular acceleration of the large sprocket. b) Calculate the number of revolutions for each sprocket during the acceleration. di

Activity 4 - Additional Practice: Gas mileage, in miles per gallon, was measured for a random sample of 9 2019 Canyonero SUV's. It is reasonable to assume that the gas mileage for these SUV's is approximately normally distributed The following are the miles per gallon for each of the 9 SUV's: 16.5, 17.2, 17.1, 17.3, 16.9, 16.7, 17, 17.1, 16.7 1. Construct a 90% confidence interval for the mean gas mileage for the 2019 Canyonero SUV. 2. Please explain why the conditions are met in this problem to construct your confidence interval above. 3. The EPA gas mileage rating for the 2019 Canyonero is 17.3 miles per gallon. Explain whether the rated mileage may be equal to the mean mileage, based on the confidence interval you created above. 4. You want to construct a 90% confidence interval for the population mean gw mileage for the Canyonero that has a margin of error of no larger than 15. How large of a random sample of Canyoneros do you need to take to ensure your margin of error is no larger than 0.157

Develop the formulas starting from the left calculating towards the right hand side in each case. (you may ignore the effect of the mass for the sake of simplicity for this test) 19 • Draw the shear force and bending moment diagrams Using the diagrams create a free body diagram in the section where the bending moment is a maximum and determine the maximum bending moment. Indicate the distance at which this moment occurs on the diagram. b) If the stress in the bending stress in the beam at the point where the moment is at its maximum if a W200 x 22 (Appendix B) beam is used and bending occurs across its x-x axis
