8x5 multiplies to be 40, and adds up to be 13.
solution:
solid spindle ab:
c= 1/2ds = ½(1.5) = 0.75in.
j= π/2c1= π/2(0.75)2 = 0.49701 in4
jmax = Tc/j
tab=jtal/c = (0.49701)(12)/0.75 = 7.952
sleeve cd = c2 = 1/2d2 = ½(3.0) = 1.5in
j = π/2(c24 – c14) = π/2(1.54-1.254) = 4.1172 in4
tab = jtl/c2 = (4.1172)(7)/1.5 = 19.213 kip.in
You multiply the exponent
Remember to MULTIPLY exponents (not add them) when you are raising a power to a power. In this case, (−3x3y2)4 = (−3)4(x3)4(y2)4 = −34 · x3·4 · y2·4.
Tan0 = opposite/adjacent =8/15
Therefore opposite(o)= 8
adjacent(a)= 15
Considering Hypotenuse
= √(o2 + a2)
= √[(8)2 + (15)2]
= √289 = 17
Sin0 = opposite/ Hypotenuse
= 8/17
Sin0=8/17
6+5 = 11 So we need to add them
