Claims (1)

Disclaimer (all) which will not appear on the advertisement page: page 1 of the number 1 disclaimer 1.The experimental set for determination of the modulus of the young in a wire consists of a platform (1), a small pulley attached to a scale needle (2), a circle scale set (3), a wire (4), a pair of pulleys (5) and a mass ( 6) There are specific characteristics as follows The experimental set for determination of the modulus of young in a wire consists of a platform (1), a metal box. There is a perpendicular metal part of the box on one side for fixing the wire (4). The other side of the platform (1) is used to hold the pair (5) of the two pulleys with The large and small pulleys are joined together by the grooves of the small pulleys for wire harnesses (4), and the large pulleys for attaching belts to A small pulley attached to a scale needle (5) mounted on a stand of a circular scale set (3), where the scale hand can be rotated several turns to show the wire holding distance (4) from the position of the scale needle. Where Z on the circle scale of the circle scale set (2), the lower end of the wire (4) is attached to the freely hanging mass (6) and can be added or Can reduce the value of the mass When starting up, take the mass (6), attach the lower end of the wire (4), and then pass the wire (4) through the small groove of the pair pulley (5). Record the starting position from the pointing needle position. On the scale of the circle scale set (3), add mass (6) to increase the tensile force of the wire (4), read the value of the pointer on the circle scale set (3), perform the mass increase experiment and record the results. Until the end of the trial
