Manufacturing Tolerance Calculation for Bushing Blueprint

What is the allowable manufacturing tolerance for a bushing where the outside dimensions shown on the blueprint are: 1.0625 + .0025 -.0003?

a) 0.0025
b) 0.0003
c) 0.003
d) 0.0022

Answer:

The allowable manufacturing tolerance for the bushing with specified dimensions and tolerances is calculated by subtracting the lower limit from the upper limit, which yields 0.0028. However, this calculated value does not match any of the options provided, suggesting either a mistake in the question or options.

Explanation: The question pertains to a manufacturing specification for an engineering component, specifically a bushing. The blueprint specifies the outside dimensions of the bushing as 1.0625 with a positive tolerance of +0.0025 and a negative tolerance of -0.0003. To find the allowable manufacturing tolerance, you calculate the difference between the upper and lower limits set by the tolerances.

The upper limit of the bushing's size, according to the blueprint, would be 1.0625 + 0.0025 = 1.0650. The lower limit would be 1.0625 - 0.0003 = 1.0622. The allowable manufacturing tolerance is the range between these two limits, which can be found by subtracting the lower limit from the upper limit: 1.0650 - 1.0622 = 0.0028.

However, the value obtained (0.0028) is not one of the options provided in the question. There might be a mistake in the question or the provided options. If considering the closest given option to the calculated value, 0.0030 would be the most appropriate answer, but it does not exactly match the calculated tolerance.
