Explanation:
Uniform Pressure Theory and Uniform Wear Theory:
- The Uniform Pressure Theory states that the pressure distribution on the friction lining of a clutch or brake is constant across the surface. This theory is applicable only when the friction lining is new, and the pressure distribution is not affected by wear.
- The Uniform Wear Theory, on the other hand, assumes that the pressure distribution changes as the friction lining wears out. This theory is applicable when the friction lining gets worn out, and the pressure distribution is affected by wear.
Friction Radius:
- The friction radius is the effective radius at which the clutch or brake operates. The friction radius for new clutches is slightly greater than that of worn-out clutches due to wear and tear.
Life of Friction Lining:
- The life of the friction lining depends on several factors, including the operating conditions, design of the clutch or brake, and the type of material used for the lining.
- A major portion of the life of the friction lining comes under the Uniform Wear Theory, as the pressure distribution changes as the lining wears out.
The Wrong Statement:
- The wrong statement is option 'D', which states that a major portion of the life of the friction lining comes under the Uniform Pressure Theory. This statement is incorrect since the Uniform Pressure Theory is applicable only when the friction lining is new, and the pressure distribution is not affected by wear. However, as the lining wears out, the pressure distribution changes, and the Uniform Wear Theory becomes more relevant.
