a)By the principle of moments;
60Nx30cm= Fx6cm
F= (60x30)/6= 300N.
b)V.R of the lever system= effort arm/load arm =30cm/6cm= 5
V.R of the hydraulic system= area of load piston/area of effort piston= 12cm2/4cm2= 3
Therefore, the combined V.R= 5x3= 15.
c)Pressure at A1= Pressure at A2
300N/4cm2 =L/12cm2
L= (300*12)/4 =900N.
