Fig 42
sinθ= S/L ； cosθ = H/L ； tanθ = sinθ/cosθ = S/H ； H = S/tanθ
Ex1：
UNIT-CHICE model is 30mm width (S = 15mm)；angle 90 degree；the piece 2mm
thickness (actual calculation usesμas unit)
Calculation :
(1) 90 ÷2 = 45
(2) sin45 = 0.707；cos45 = 0.707；tan45 = 1
(3) H = 15000（μ）÷1 =15000（μ）
(4) 15000（μ）－ 2000（μ）= 13000（μ）
(5) 13 mm Pressing Down Depth∴
EX2：
UNIT-CHICE model is 30mm width ( S = 15mm Actual calculation usesμas unit)；
angle 150 degree；what is the pressing down depth H?
Calculation :
(1) 150 ÷2 = 75
(2) sin75 = 0.9659；cos75 = 0.2588；tan75 = 0.9659÷0.2588 = 3.7322
(3) H = 15000（μ）÷3.7322 = 4019.077
(4) 4019.077（μ）－ 2000（μ）= 2019.077（μ）
(5) ∴2.019 mm Pressing Down Depth
