Case 5 : Mass on Rollers

Input Data
M = 800 kgs
V = 1.2 m/sec
U = 0.3
S = 0.05 M
X = 120/Hr

Formuale
Ek = m x v^2/2 = 576
Ep = m x g x S x m = 11.7
Et = Ek + Ep = 587 NM
Et/Hr = Et x X = 70531
Me = 2 x Et/V2 = 815

m is coefficient of friction of still asumed 0.2
We select AD-42-75-SOFT

Applications : Automated transfer lines for TV, Electronic Equipments, Billet.
