Vector Force Practical Board 力的合成板
For you to practice how to calculate the resultant force formed and the angle of force affect the resultant force. This board contains a metal spring which is stretched by two angle of force . The extension of spring is indicated by a marked rule, and the two stretching forces can be applied by a Newton balance to obtain the size of force directly. There is a sucker under the pulley to fix its' in position.
Size of board : 330 x 330mm
