To open a stuck jar lid, wearing rubber gloves sometimes works. why does that ? you can exert a greater torque by exerting a lower force tangential to the lid. the coefficient of static friction between the rubber and the lid is likely to be greater than the coefficient of static friction between your hand and the lid. you can exert a greater torque by exerting a lower force tangential to the lid. the coefficient of static friction between the rubber and the lid is likely to be lower than the coefficient of static friction between your hand and the lid. you can exert a lower torque by exerting a greater force tangential to the lid. the coefficient of static friction between the rubber and the lid is likely to be greater than the coefficient of static friction between your hand and the lid. you can exert a greater torque by exerting a greater force tangential to the lid. the coefficient of static friction between the rubber and the lid is likely to be greater than the coefficient of static friction between your hand and the lid.
