WebStep 1: Chord length = 3 ⇒ 2 (2) sin (θ/2) = 3 Step 2: Solving this, we get: sin (θ/2) = 0.75 ⇒ θ/2 = sin -1 (0.75) = 0.848 ⇒ θ = 1.696. Step 3: Arc length = radius × central angle = 2 × 1.696 = 3.392 units Thus, arc … WebObserve the schematic of a curve. It should be apparent that if the entire chord is on tangent, the mid-ordinate will be zero. It should also be apparent that as the chord moves off the tangent and onto the spiral, mid-ordinate will increase until the entire stringline is within the full body of' a curve. Within
