Physics Experiment: Measuring Cylinder Dimensions

Experiment Aim and Setup

• This experiment aims to measure the diameter and height of a cylinder using a vernier caliper and calculate the curved surface area and volume of the cylinder.
• The vernier caliper used has a range of 0 - 150 mm, with a least count of 0.02 mm.
• The caliper has both internal and external jaws for measuring internal and external diameters.
• It also includes a depth measuring blade.
• The tool features a metric scale and an imperial scale.
• The vernier scale has 50 divisions.
• The main scale has divisions of 1 mm.

Observations

• The experiment involves recording the main scale reading and the vernier scale reading that coincides with a mark on the main scale.
• The vernier scale reading is then multiplied by the least count to find the vernier scale reading in millimeters.
• The final reading is obtained by adding the main scale reading and the vernier scale reading.
• The experiment records two readings of the diameter for accuracy and calculates the average.
• The experiment records three readings of the height and then calculates the average.
• The experiment measures the zero error of the vernier caliper, which is the difference between the zero mark on the vernier scale and the zero mark on the main scale.
• The experiment calculates the correction (C) for the zero error.

Calculations

• The radius of the cylinder is calculated by dividing the diameter by two.
• The curved surface area of the cylinder is calculated using the formula: A = 2πrh, where r is the radius and h is the height.
• The volume of the cylinder is calculated using the formula: V = πr²h, where r is the radius and h is the height.

Results

• The experiment concludes with the calculated values for the radius, height, curved surface area, and volume of the cylinder.
• The results are reported in centimeters.

This quiz focuses on the aim and setup of a physics experiment designed to measure the diameter and height of a cylinder using a vernier caliper. Participants will learn how to calculate the curved surface area and volume of the cylinder, using precise measurements and observations from the caliper.
