Which surface is to be smoother, the inside of the .500" diameter hole or the 15° tapered conical surface? 3. Which machining process, if any, is specified for the surface texture symbol applied to the 1 5" diameter face surface? are the values in microinches or micrometers? 4. For the surface texture symbols indicated on this drawing, 5. What lay symbol is indicated on one of the surface texture symbols? 6. Do any of the surface texture symbols indicate the surface texture should be obtained without removing material? Review questions on previous units: 7. Are there any cutting-plane lines shown on this drawing? 8. What material is specified for this part? 9. What scale are the main views on the original drawing? 10. How many threaded features does this part have? 11. The details are shown in two circles made with what line type? 12. Looking over the entire drawing, how many dimensions are expressed using the limit method? 13. There is a solid, equilateral triangle floating next to some dimension values. What tolerance applies to those values? 14. What is the maximum diameter of the drill spot that may exist at the bottom of the main hole in this part? 15.

4- 100 ft tape was used to measure line DF; if the correct tape length is 100.05 ft, the field temperature is 37°, the standard temperature is 20°, the thermal expansion coefficient is 0.00004, Calculate the corrected distance if the measured one is 425.50 ft.

Statement: The figure below shows three cycles of time-varying loading on a double D-ring held together with a single bolt and nut. The figure shows both the bolt tensile force and the member compressive force. QUESTION 1 - Based on the figure, give the minimum and the maximum of the external load, P?

Refer to drawing 21A033, what is dimension G?  (Please note that you can't just assume the hub protrudes equally on both sides as it may not)   All abbreviations are standard

Hello, the stress and cycles required for this question is Stress 1 = 420MPa at 7 cycles, Stress 2 = 360MPa at 65 cycles and Stress 3 = 130MPa at 325 cycles. Use the first three cycles (which shows how many cycles at that stress level to failure) to calculate when the specimen will fail if it underwent test of 7 cycles at 420MPa, then undergoes 360MPa for 65 cycles and finally 130MPa at 325 cycles. Will the specimen fail? Please show calculations of failure

Which of these expressions represents the value of G for a 90 degree elbow if the degree of fit is 45 degree, the radius of the welding elbow is 10 inches, and the outside diameter is 14 inches. A - 45x(10+7) B - 45x(10+14) C   45x(10x7)

Refer to drawing 21A033, What is the wall thickness of the hub?   All abbreviations are standard

At operating stress of 420MPa, the number of cycles to fail a specimen is 65 cycles. At operating stress of 360MPa, the number of cycles to fail the specimen is 390 cycles, and at operating stress of 130MPa, the number of cycles to fail the specimen is 11,900 cycles. A test sequence as follows is designed: first, operating stress of 420MPa for 7 cycles, second, operating stress of 360MPa for 65 cycles, and third, operating stress of 130MPa for 325 cycles. Determine at what number of cycle and which operating stress level the specimen would be expected to fail if the above sequence is repeated.
