BIO? While hovering, a typical flying insect applies an average force equal to twice its weight during each downward stroke. Take the mass of the insect to be 10 g, and assume the wings move an average downward distance of 1.0 cm during each stroke. Assuming 100 downward strokes per second, estimate the average power output of the insect.

Solution 59E Step 1: Power is rate of doing work and it can expressed mathematically P = Net work/time P = F × S/t Here,F is force acting on the system and v is the velocity of the system. Step 2: Given data: mass of insect = 10 g = 0.01 kg. average downward distance during each stroke S = 10 cm = 0.01 m. Time taken for one cycle is 1/100 s.
