1.	Calculate the value of the torque when 89 N force is applied perpendicular to a 78 m length of stick fixed at the center.(a) 6942 N-m(b) 3000 N-m(c) 1000 N-m(d) 4470 N-mI have been asked this question in my homework.The doubt is from Methods of Starting Electric Motors in section Starting of Electric Drives
Answer» The correct option is (a) 6942 N-m To EXPLAIN I would SAY: Torque can be calculated using the relation T = (length of STICK) × (Force applied) = r×F×sin90. F is given as 89 N and r is 78 m then torque is 89×78 = 6942 N-m. (the angle between F and r is 90 degrees).
