A serviceable spring balance
The quality of rubber deteriorates rather rapidly in unfavourable climatic conditions; a coiled steel spring is preferable. The pattern defined has been found satisfactory. The coil is protected from injure by enclosing it in a tube.
The reading is made at the bottom of the tribe on a graduated wooden plunger. First wind the spring attach it by a screw eye to a piece of dowelling which will fit into the tube selected (bamboo or plastic).Fasten the other end of the spring by a wire staple to a wooden stick which will glide in the tube. Fix the dowelling to the top of the tube and put in into it a hook for suspending the balance. Screw one more hook into the wooden plunger which can now be graduated.
a small block of weight 10 Ib is placed on an inclined plane which makes an angle of 30 degree with the horizon. resolve the gravitational force.
