"How to measure and express force" Force and Machinery PPT Courseware 3
example
Draw a schematic diagram of the force in the question: lift a bag of grain with a force of 200N.
1. Find the point of action (that is, the point where the force-exerting object acts on the force-receiving object)
2. Draw a line segment along the direction of the force at the point of action. The length of the line segment indicates the magnitude of the force.
3. Draw an arrow at the end of the line segment to indicate the direction of the force, and use the starting point of the line segment to indicate the point of action of the force.
4. Indicate the size of the force.
Schematic diagram of force:
(1)Definition: Use a straight line segment with an arrow to connect _________
Express it. (The length of the line segment indicates the magnitude of the force, and the arrow indicates the direction of the force)
(2) Practice:
① Determine the force-bearing object: represented by □ or ○;
② Determine the action point of the force: contact point;
③Draw a line segment along the direction of the force at the point of application of the overforce:
④Draw an arrow at the end of the line segment:
⑤ Mark the symbol and magnitude of the force next to the arrow.

1. The length of the spring is 10 cm. When the spring is pulled with a force of 1 Newton, the length of the spring is 11 cm. When the force of 5 Newton is used to pull it, the length of the spring is: ( )
A. 10 cm; B. 15 cm; C. 50 cm; D. 55 cm.
2. As shown in the figure, the pointer of the spring dynamometer being used points at a certain position. The measuring range of this spring dynamometer is _____N, and the graduation value is _____N. As shown in the figure, the pulling force of the hand is _____N.
3. When using a spring scale, the following practices are correct: ( )
A. The spring scale should be adjusted before use so that its pointer is aligned with the zero point;
B. The spring scale must be placed vertically and not tilted;
C. When in use, the spring, pointer, and hook of the spring scale must not rub against the outer shell;
D. When using, it must be noted that the measured force must not exceed the measuring range of the spring scale.
