Answer :
Final answer:
The maximum compressional load at which fracture occurs is 76500 N.
Explanation:
The maximum compressional load at which fracture occurs can be calculated using the formula:
Maximum Compressional Load = Ultimate Compression Strength * Minimum Cross-sectional Area
Plugging in the given values, we have:
Maximum Compressional Load = (17 x 107 N/m²) * (4.5 x 10-4 m²)
Simplifying the expression, we get:
Maximum Compressional Load = 76500 N
Therefore, the correct answer is b) 76500 N.
