Question

ADDITIONAL INFORMATION

TABLE 1 IS THE EXPERIMENT DATA. THE BOLT, THE DIMENSION OF THE BOLT. USING THE INFORMATION FROM TABLE 1 I'M SUPPOSED TO MAKE ANOTHER TABLE SHOWING make another table that reports tu, ty,tys both calculated from the data in table 1 using the equation from number 5 (torsional yield strength) and another column with the estimated calculations using section 7 equation and getting the information(torsional yield strength numbers from the bolt chart for each specimen)

Next in the table find tus (Calculated from the data using # 6 equation (ULTIMATE TORSIONAL STRENGTH below then and an estimated calculation using #8 equation ultimate torsional strength using the information in the bolt chart). All the dimensions and information from table 1 is to make a second table 2 with the information above.

_______________________________________________________________________________________________

my calculations in table 2 are not correct i need to redo Table 2.

what is wrong with my data see instructions in photo 2 second bullett point -------

make another table that reports Tu, Ty,tys (calculated from the data using section 5 and estimated using section 7) and tus (Calculator from the data using section 6 and estimated using section 8)

The doua mi. D, and J for all 4 specimens are listed in Table 1 below. These figures were determined by using the formula's below. The demand daai are found by measuring the minor and major diameters of the threaded section in inches. Then the bolt diameter is calculated by taking the average of the drain and doi These measurements were taken before doing the test.

T, is the torque to yield which was calculated by noting the torque-rotation point where the bolt rotation continues with rapidly diminishing increase torque. T, is the ultimate torque which is the maximum torque the bolt could withstand prior to fracture.

Answer 1

The corrected table-2 is hereunder:

Specimens Bolt/Identity	Ultimate Torque (Tu)	Yield Torque (Ty)	Torsional Yield Strength (Tys)		Ultimate Torsional Strength (Tus)
			Tys=Ty*D/2J	Tys=0.5*Syt	Tus=Tu*D/2*J	Tus=0.75*Sut
