I'm trying to calculate the static reaction force on cylinder supported by two rollers due to the weight of the cylinder. I found that the reaction force is inversely proportional to the Cosine of the contact angle, but what does it mean? when the contact angle is close to 90 degrees is the reaction force much higher then the weight of the cylinder? if the weight of the cylinder is the source of the reaction forces how can it be lower than the reaction forces?
