3. 8/16 points Previous Answers SerCP11 8.1.P.001. В му A doctor opens a 1.25 m wide door by pushing on it with a force of 39.5 N directed perpendicular to its surface. HINT (a) What magnitude torque (in N.m) does she apply about an axis through the hinges if the force is applied at the center of the door? 24.69 Nm (b) What magnitude torque (in N.m) does she apply at the edge farthest from the hinges? 59.25

Answer 1

doctor wide, Door is d=j 25 m F= 39.5 Ni perpendicular applicd force to swifece क) । center e. she whe ferce on at point the A, is Torque given by T= FYsin0 hori 0= 90,D sing =1 so 3.६५(/289) 24.69 N-m %1 9) O The edge ferrthest from hinge wowd be at distance di so at point B s say) SO T= 3905 X 1025= 49.37 N-m 49.37 N-m
