The tensile strength of spider silk is about 1150 MPa, which is 1.15 x 10^9 N/m². 

<span>So given that the diameter of the spider silk is 0.15 mm or 1.5 x 10^-4 m. The cross sectional area is approximately: </span>

<span>A = πr² = (3.14)(1.5 x 10^-4 / 2)² = 1.767 x 10^-8 m² </span>

<span>So this means that the amount of force we can apply before the the silk thread is broken is: </span>

<span>F = PA = (1.15 x 10^9)(1.767 x 10^-8) = 20.32 N </span>

<span>F = mg, so m = F/g = (20.32)/(9.81) = 2.07 kg!!! </span>

The figure shows the front side of a purse in the shape of a trapezoid.
attashe74 [19]
For this case, what you must do is take out the area of two triangles and add it to the area of a rectangle to find the total area.
 We have then:
 Triangle area:
 A = (1/2) * ((13-9) / (2)) * (10) = 10 in ^ 2
 Rectangle area:
 A = (9) * (10) = 90 in ^ 2
 Total area:
 At = 2 * (10) + 90 = 110 in ^ 2
 answer:
 110 in²
