Homework Statement
A spider is caught in the midpoint of a spider thread. The thread breaks under a stress of 8.2E8 N/m^2 and a strain of 2.00. Initially, it was horizontal and had a length of 2.00 cm and a cross-sectional area of 8.E-12 m^2. As the thread was stretched under the weight of the insect, its volume remained constant. If the weight of the insect puts the thread on the verge of breaking, what is the insect’s mass?
Homework Equations
stress=F/A
A=cross sectional area
The Attempt at a Solution
Stress*A/g=w
I know I'm missing a key point here because I do not take in account the length of the wire, but how does the length of wire affect this problem?
