After resolving the forces into their components as shown, we can write the ®rst condition for equilibrium: ‡ 3 Æ Fx ˆ 0 becomes FT2 cos 5:08 À FT1 cos 108 ˆ 0 4 Æ Fy ˆ 0 becomes FT2 sin 5:08 ‡ FT1 sin 108 À 90 N ˆ 0 ‡ When we evaluate the sines and cosines, these equations become 0:996FT2 À 0:985FT1 ˆ 0 and 0:087FT2 ‡ 0:174FT1 À 90 ˆ 0 Solving the ®rst for FT2 gives FT2 ˆ 0:990FT1 . Substituting this in the second equation gives 0:086FT1 ‡ 0:174FT1 À 90 ˆ 0 from which FT1 ˆ 0:35 kN. Then, because FT2 ˆ 0:990FT 1 , we have FT2 ˆ 0:34 kN: CHAP.

To ®nd Ff , the sliding-friction force, we use Æ Fx ˆ 0. 7 (a) We have 200 cos 30:08 À Ff ˆ 0 so that Ff ˆ 173 N. Then, k ˆ Ff =FN ˆ 173=400 ˆ 0:43: (b) We have 200 cos 30:08 À Ff ˆ 0 so that Ff ˆ 173 N.

Inertia is the tendency of a body at rest to remain at rest, and of a body in motion to continue moving with unchanged velocity. For several centuries, physicists have found it useful to think of mass as a representation of the amount of or quantity-of-matter.
