Question

d) Which of the following statements is false: 11 point ? Spring surge is a phenomenon experienced when a spring supported in on end is disturbed and a compression wave is created and travels back and forth, Resonance in ? spring is when the frequency of the applied force is greater than twice the natural frequency of the spring The hook in extension springs experience, normal stress due to asil loading and bending as well as sbear stress due to torsion D Manufacturers prefer to manufacture Extension springs with some initial tensions d) List two types of springs 11 point) compgressin springs I pia e) Explain the difference between extension springs and commpression springs. [I point

Explanation / Answer

ANSWER 1:- (b)

Explanation: - resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations equals the system's natural frequency of vibration.

ANSWER 2:-

1. Extension spring

2. Compression spring

ANSWER 3:-

The main difference is that extension springs are meant to hold two things together while compression springs are designed to keep components from coming together. Compression and extension springs are in fact vastly different because they do different jobs.
