Helical Spring Experiment Concepts

The video tutorial demonstrates how to determine the spring constant of a helical spring by plotting a graph between load and extension. It outlines the materials required, the procedure for adding and removing weights, and how to record the corresponding scale readings. The tutorial explains how to calculate the spring constant from the observed data and verify it by plotting a graph, which should result in a straight line. The slope of this line gives the spring constant, confirmed to be 35 N/m.

What is the primary objective of the helical spring experiment?

• To find the spring constant by plotting a graph

• To calculate the density of the spring

• To measure the length of the spring

• To determine the weight of the spring

Which of the following is NOT listed as a required material for the experiment?

• 50 gm weights

• Rigid stand

• Metre scale

• Thermometer

What is the first step in setting up the experiment?

• Add a 50 gm slotted weight

• Record the reading on the scale

• Fix the helical spring on the rigid stand

• Hang a 50 gm weight hanger at the end of the spring

What should be done after adding a 50 gm slotted weight to the hanger?

• Fix the spring on the stand

• Remove the weight immediately

• Add another 50 gm weight

• Note the reading on the scale

How many additional 50 gm weights are added during the experiment?

• Two

• Four

• One

• Three

What happens to the pointer when a weight is removed from the hanger?

• It moves upward

• It remains stationary

• It oscillates

• It moves downward

What is the final step in the procedure after removing all weights?

• Calculate the spring constant

• Add more weights

• Fix the spring on the stand

• Record the initial reading

How is the spring constant determined from the graph?

• By finding the slope of the graph

• By counting the number of weights

• By calculating the area under the curve

• By measuring the length of the spring

What is the calculated mean value of the spring constant?

• 25 N/m

• 40 N/m

• 30 N/m

• 35 N/m

What does the straight line on the graph indicate?

• The spring constant is zero

• The spring is broken

• The relationship between load and extension is linear

• The spring is not elastic
