A steel plate used for polymer forming is to be bent into a circular shape having an inside radius of 8 m. What maximum thickness can be used for the plate if the normal stress is not to exceed 254 MPa? Assume that the modulus of elasticity for the steel is 207 GPa.

(b) The water is siphoned out of the tank shown in Figure 4 (b). Determine the flow rate from the tank and the pressures at points (1) and (2).

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)?   https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5.  1 pass 2 fail 3 fail 4 pass

The U-tube shown in Figure Q3 (a) is rotated about one of its arms at an angular speed of o rad/s. At o = 0 rad/s, the U-tube contains 20-cm-high alcohol in both arms Q3 (a) Determine the new o when the elevation difference between the fluid surfaces in the two arms is 30 cm.

That is the answer I already have, I am lookinf for the answers to the blanks in the image

For the last portion, why do you divide by two?

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

Given the points A( – 5, 6, – 4), B( – 2, — 10, 6), and C'(4, 0, 5), find (a) the angle between AB and AC, (b) the angle between BA and BC, and (c) the angle between CA and CB. (a) ZBAC = 29.9 (b) ZABC 42 (c) ZACB = 95.225 Submit Question X X > 8

What’s the correct answer please?
