When a load is applied gradually, the bar has time to deform and the stress is lower.<\/p>\n<p>The ratio of the stresses produced by a suddenly applied load and by a gradually applied load on a bar is called the impact factor. The impact factor is a dimensionless number that is greater than 1. The impact factor depends on the material properties of the bar and the shape of the load.<\/p>\n<p>The following is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: $\\frac{1}{4}$. This is the correct answer. The impact factor is greater than 1, so the stress produced by a suddenly applied load is greater than the stress produced by a gradually applied load.<\/li>\n<li>Option B: $\\frac{1}{2}$. This is not the correct answer. The impact factor is greater than 1, so the stress produced by a suddenly applied load is greater than the stress produced by a gradually applied load.<\/li>\n<li>Option C: 1.
