Forces acting at a point in statics
For vectors A and B, the vertical components can be determined using the sine of the angle and the horizontal components can be analyzed using the cosine of the angle. Set number of decimal places or For average, standard deviation - Use excel functions to check yourself, but understand what equations excel is using. An analysis of the horizontal components shows that the leftward component of A nearly balances the rightward component of B. Compare both result that obtain by using the calculation method and polygon method choose either set of data. The data in the table above show that the forces nearly balance. It is shown that there are weight and normal force. Use this information and the diagram below to determine the tension in the wire for each orientation. Figure 1: Diagram of apparatus used to measure the static coefficient of friction between various materials. The vector sum of all the forces is nearly equal to 0 Newton. Since the angle between the cables is degrees, then each cable must make a degree angle with the vertical and a degree angle with the horizontal. The equation should be numbered, and separated from text on either side with a blank line. We could say it's "close enough for government work.
Show equations for how to calculate the coefficient of friction from inclination angle. Once the components are known, they can be compared to see if the vertical forces are balanced and if the horizontal forces are balanced.
The vector sum of all the forces is nearly equal to 0 Newton. The sign weighs 50 N.
To illustrate this, consider a Newton picture held by three different wire orientations as shown in the diagrams below. Use this information and the diagram below to determine the tension in the wire for each orientation.
The cos value will be less than 1 and it will affect the calculation that leads to less weight in scale.
All graphs should have a figure caption like this below them. Figure 1: Diagram of apparatus used to measure the static coefficient of friction between various materials. What is the weight of the sign? If the any two of these three are known, then the third quantity can be determined using trigonometric functions.
