現在探討有個凸輪，
開始時先在0°至100°區間滯留之後提升，
並且在200°至260°區間再次滯留，
其高度（衝程）為5公分，
其餘260°至360°則為返程。
升程採用等加速度運動，
返程之運動型式若為等速度運動的話，
則利用dewell()及plot_dewell()兩個程式，
以每10°計算一次，
並繪出其位置、速度、加速度與凸輪迴轉角度的關係圖：
>> plot_dwell(0:10:360,5,[2 1],[100 200 260])

y為從動件在不同迴轉角度，
垂直移動的高度。
yy為從動件的垂直運動速度。
yyy為從動件的垂直加速度。
題目二：
若今天有一個凸輪半徑15㎝，
以順時針方向旋轉。
從動件為梢型，
垂直接觸凸輪，
長為10㎝。
從動件之運動依照上一題之運動型式，
100°～200°、260°～360°各為升程及返程時的對應迴轉角度。
升程為等加速度運動，
返程仍設定為等速運動。

所計算出來各對應的值，
為梢型從動件和凸輪接觸的座標。
因為偏置為零，
故所有從動件之延長線，
均會交於基圓的圓心。
