where did the name arm and hammer come from
Arm & Hammer The original Arm & Hammer logo usage dates back to the 1860s. James A. Church, son of Dr. Austin Church, ran a spice business known as Vulcan Spice Mills. According to the company, the Arm and Hammer logo represents Vulcan, the Roman god of fire and metalworking.[1]
Pound-foot (torque) The name "pound-foot", intended to minimize confusion with the foot-pound as a unit of work, was apparently first proposed by British physicist Arthur Mason Worthington.[1] However, the torque unit is often still referred to as the foot-pound (ftâ‹…lbf).[2]
