2 The greater the force, the greater the stretch Force ~ Stretch, F ~ x, F = k ∙ x F 1 /x 1 = k = F 2 /x 2 F 1 /x 1 = F 2 /x 2 x 2 ∙ F 1 /x 1 = x 2 ∙ F 2 /x 2 x 2 ∙F 1 /x 1 = F 2 x 2 ∙F 1 /x 1 / F 1 = F 2 / F 1 The Stretch is Proportional to the Force x 2 / x 1 = F 2 / F 1

4 Right triangle θ - theta opp/hyp = opp/hyp = sin θ (sine) adj/hyp = cos θ (cosine) opp/adj = tan θ (tangent) SOHCAHTOA Triangles

5 Solving a Triangle Finding all three sides and all three angles Given: – AB = 5.2 meters – Angle A = 70° – Angle C = 90° Find – BC = – AC= – Angle B = sin θ = opp / hyp sin θ = BC / AB AB ∙ sin θ = BC BC = 5.2 ∙ sin 70°= 5.2 ∙.940 = 4.89 meters

6 Finish Solving the Triangle Third Angle: ∆ = 180° B = 180 Angle B = 20° tan 70° = BC/AC AC = BC/tan 70° = 4.89 / 2.74 = 1.78 meters
