Final answer:
To calculate the weight of the load, we need to consider the strain on the copper wire and use the formulas for stress and weight. Assuming the wire is made of copper, we can find the strain, stress, and weight using the given values.
Step-by-step explanation:
To find the weight of the load, we need to consider the stretching of the copper wire due to the acceleration.
First, we need to calculate the strain on the wire. The strain is given by the change in length divided by the original length. In this case, the wire stretches by 1.0% of its original length, so the strain is 0.01.
Next, we can calculate the tensile stress on the wire using the formula stress = strain × Young's modulus. Assuming the wire is made of copper, the Young's modulus is approximately 120 GPa (1 GPa = 1 × 10^9 Pa).
Finally, we can determine the weight of the load using the formula weight = mass × acceleration. Assuming the acceleration is 2.0 m/s², we can rearrange the formula to solve for the weight. By substituting the mass of the load with the weight of the load, we find that the weight of the load is equal to the mass of the load multiplied by the acceleration due to gravity.
