Define elasticity.
Property of object that enables it to return to its original shape after an applied force is removed.
Define Hooke's law.
extension of a spring is directly proportional to the stretching force.
What meant by elastic limit?
Maximum extension of stretching force.
A load of 2.5 N extends spring A by 20 cm. Find the spring constant, k.
12.5 N/m
A 30 cm spring is compressed to 25 cm when a load of 300 g is placed on it. What is the spring constant, k of that spring?
60 N/m
Original spring is 10 cm. With a load of mass 300 g, the spring extended to 16 cm. What is the load required to extend the spring to 20 cm and what is the spring constant, k.
500 g / 0.5 kg
k = 50 N/m
Given that spring constant of spring A is 12.5 N/m and spring B is 8.3 N/m. If both are connected with same load, 50 N, how much the extension for each spring and with one is more stiffer.
A = 4 cm
B = 6 cm
A more stiffer than B
Three springs are connected in series arrangement with a load 0.2 kg extend 4 cm each. When the load is change to 0.3 kg, what is the length of spring? Calculate the length of springs when arrange in parallel.
[Original length of spring without load is 16 cm].
length of springs in series = 66 cm
length of springs in parallel = 18 cm
Spring P, Q and R are arrange in parallel. Another spring S and T and arrange in parallel just below the spring P, Q and R. All the springs are identical. Original length of each spring is 12 cm. With a load of 200 g, the length becomes 16 cm. Calculate the length of the springs in the system when using 500 g.
32.3 cm / 0.32 m
