Practical Examples:
Example 1: Car Suspension
A car's suspension system uses a spring with a spring constant of 500 N/m. If the spring is compressed by 0.1 m, calculate the force exerted by the spring.
Solution: F = k × x = 500 N/m × 0.1 m = 50 N
Example 2: Trampoline
A trampoline has a spring constant of 200 N/m. If a person weighing 70 kg (approximately 700 N) jumps on the trampoline, causing it to depress by 0.5 m, calculate the force exerted by the trampoline's springs.
Solution: F = k × x = 200 N/m × 0.5 m = 100 N
Example 3: Door Closer
A door closer uses a spring with a spring constant of 300 N/m. If the door is opened by 0.2 m, calculate the force exerted by the spring to close the door.
Solution: F = k × x = 300 N/m × 0.2 m = 60 N
Example 4: Pogo Stick
A pogo stick uses a spring with a spring constant of 1500 N/m. If the spring is compressed by 0.3 m when a person jumps, calculate the force exerted by the spring.
Solution: F = k × x = 1500 N/m × 0.3 m = 450 N
Example 5: Medical Device
A medical device uses a spring with a spring constant of 100 N/m. If the spring is compressed by 0.05 m to apply pressure, calculate the force exerted by the spring.
Solution: F = k × x = 100 N/m × 0.05 m = 5 N
