Torque Explained

By definition, if we calculate work as a vector force, exerted in a line witch is straight. Engines spin around an axis. As well as nuts and bolts when they are tightened or loosened. Torque Horsepower meaning!

What is engine torque?

The expression of this rotational or twisting force around an axis is also  called torque, which is measured in units of force times distance from the axis of rotation. If you have a one foot-long wrench and you make her longer with  a force of 10 pounds on the end of it then you apply a torque of 10 pound-feet (10 lb-ft). If the wrench were 2 feet long, the same force would apply a torque of 20 lb-ft. An engine is said to make “200 lb-ft of torque”. It means 200 pounds of force on a 1-foot lever is needed to stop its motion.

The best way to increase torque is to increase engine displacement. Horsepower should follow the torque increase, provided the cam and heads don't become limiting factors. Equipped with identical heads and cam, this World Products 540ci Rat motor gained 67 lb-ft over its 31ci-smaller brother, but made just 13 more peak horsepower, pointing to the need for a larger cam and heads.

 

Horsepower explained 

Horsepower (hp) is a power unit of measurement.  (The rate at which work is done). You can find different standards and types of horsepower. Two most common definitions in use today are the mechanical horsepower (or imperial horsepower), which for example approximately 745.7 watts; and the metric horsepower, which is approximately 735.5 watts.Torque Horsepower meaning

Term was adopted in the end of 18th century. Scottish engineer James Watt to compare the output of  engines with the power of an draft horses. What it was later expanded to include the output power of other types of piston engines. Also as well as electric motors, turbines and other machinery. The definition of the unit varied between geographical regions. Most countries now use the SI unit watt which are for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1, 2010. The use of horsepower in the EU is permitted only as a supplementary unit.
