Here are the steps to perform the experiment:
- Determine the weight (P) of the block using a dynamometer.
- Process the measurement results. Record the measurement and calculation results in Table 19 without considering the error.
- Assemble the setup according to Figure 209.
- Measure the height (h) of the inclined plane. Calculate the useful work using the formula (A_п = Ph).
- Move the block upwards at a constant speed along the inclined plane, applying force along the board.
- Measure the distance (s) that the block travels using a ruler.
- Measure the pulling force (F).
- Calculate the work done to lift the block using the formula (A_з = Fs).
- Determine the efficiency of the inclined plane using the formula $$η = \frac{A_п}{A_з} \cdot 100\%$$.
- Analyze the results and draw a conclusion.
