Question

The figure below shows a crude model of an insect wing. di 02_- m mm The mass, m, represents the entire mass of the wing, which pivots about the fulcrum, F. The spring represents the surrounding connective tissue. Motion of the wing corresponds to vibration of the spring. Suppose the mass of the wing is 0.287g and the effective spring constant of the tissue is 4.53E-4 N/m. Distance di = 3.50 mm and distance d2 = 1.66 cm. If the mass m moves up and down a distance of 1.97 mm from its position of equilibrium, what is the maximum speed of the outer tip of the wing?

Answer 1

given that di= 3.50mm, da - 1.66cm distance - 1.97 mm Vinner max = Uspring max - AS = 1.97x10m (u. 53x10 10.237x16% = 2.474995 x103 o sec - Vowler - Vinner router dinner Vouter, max - router) & Vinner, man rinner) (1.66x10²m x 2.4749958103 (3.50x103) - 0.011438 5 m/sec
