Hi all, I'm newer to this forum. I want to calculate the pulling force required to pull the load of 2 tons on a inclined surface(inclined angle is 11 degrees).Load is fitted with SKF Deep grove ball bearings. i have seen formulas to calculate pulling force to overcome friction without bearings. I need a calculation to pull a load with bearings attached. Please help. if you need any data please reply me. Thanks in Advance.
