Spider silk has a Young’s modulus of 4.0 GPa and can withstand stresses up to 1.4 GPa. A single web strand has a crosssectional area of 1.0 × 10⁻¹¹ m², and a web is made up of 50 radial strands. A bug lands in the center of a horizontal web so that the web stretches downward. 

(a) If the maximum stress is exerted on each strand, what angle θ does the web make with the horizontal?

(b) What does the mass of a bug have to be in order to exert this maximum stress on the web? 

(c) If the web is 0.10 m in radius, how far down does the web extend?
