35 N 40 N O 45 f 25 N 30 N f Three forces, each having a magnitude of 1 N, are arranged to produce equilibrium. a. Draw a sketch showing an arrangement of these forces, and demonstrate that the angle between the resultant and each of the other two forces is 60. b. Explain how to determine the angle between the equilibrant and the other two vectors. 15. Four forces, f1, 2, 3, and 4, are acting on an object and lie in the same plane, as shown. The forces f and f2 act in an opposite direction to each other, with = 30 N and 2 = 40 N. The forces f3 and f4 also act in opposite directions, with 3 = 35 N and 4 = 25 N. If the angle between fi and f3 is 45, determine the resultant of these four forces. 16. A mass of 20 kg is suspended from a ceiling by two lengths of rope that make angles of 30 and 45 with the ceiling. Determine the tension in each of the ropes. 17. A mass of 5 kg is suspended by two strings, 24 cm and 32 cm long, from two points that are 40 cm apart and at the same level. Determine the nsion in each of the strings. 35 N 40 N O 45 f 25 N 30 N f Three forces, each having a magnitude of 1 N, are arranged to produce equilibrium. a.
