Question

3. Amaterial has a mass of 95 g and 68 g before and after abrasion, respectively. If the abrasive

ratio of 1.85, find the area of abrasion

Answer 1

Area of abrasion= ($\frac{185}{100}$$\times$ 95)-($\frac{185}{100}$$\times$ 68)

Area of abrasion= 175.75- 125.80

Area of abrasion= 49.95
