ANS:C - one and half times

The ultimate strength of a material refers to the maximum stress it can withstand before failure occurs. In the case of steel, the ultimate strength in tension (pulling force) is typically higher than the ultimate strength in shear (sliding or cutting force). Therefore, the correct comparison is: Ultimate strength in tension > Ultimate strength in shear In other words, the ultimate strength in tension is generally greater than the ultimate strength in shear for steel.
