- On the part shown, specify a paralellism tolerance to make the top surface parallel to datum A within a total of .002, and with both the profile and parallelism applied to the part above what is the maximum height of the top surface to datum A? Can the MMC Modifier be applied to the feature tolerance? why or why not?arrow_forwardRefer to the Ø.8740 ± .0005 dimension. D) What is the MMC,(Maximum material condition) ? ________________________________ E) What is the LMC,?(least material condition) _________________________________ Refer to the 1.914 dimension. Where is the tolerance specified ? _________________________________arrow_forwardI need help please. Apply a dia 0.5 at MMC straightness control to the axis of the part above and draw the resultant tolerance zone and virtual size on the sketch of the produced part below. The image and question are also attached.arrow_forward
- Identify the primary, secondary and tertiary datums associated with the positional geometric tolerance placed with the Ø.875±.005 dimension?arrow_forwardFor a floating fastener application, a hole size specification of 385" minimum and .395" maximum diameter has a position tolerance specification of .010" diameter MMC. If the position tolerance is changed to .000" diameter MMC, a minimum hole diameter of must be specified with the maximum size limit remaining .395", A. .375 B. .380 C. .385 D. .390arrow_forwardRefer to the 1.914 dimension.

- Write briefly about fits and tolerances used in design. And solve this example: A medium force fit on a 50 mm shaft requires a hole tolerance of 0.025 mm and a shaft tolerance of 0.016 mm. The maximum interference is to be 0.042 mm. How will you dimension the hole and the shaft, if hole deviation is H?arrow_forwardThe diameters of shafts with a nominal size of dn = 68 mm must be within limits dmax = 68.045 mm and dmin = 68.015 mm. What are the upper deviation es. the lower deviation ei. and the tolerance Td? es ei Td 1) -0.015 +0.045 0.030 2) +0.045 -0.015 0.060 3) +0.045 +0.015 0.030 4) +0.015 -0.045 0.060arrow_forwardRefer to the 1.914 dimension.

- A stepper motor serves as the drive unit for the linear joint of an industrial robot. The joint must have an accuracy of 0.25 mm. The motor is attached to a leadscrew through a 2:1 gear reduction (2 turns of the motor for 1 turn of the leadscrew). The pitch of the leadscrew is 5.0 mm. The mechanical errors in the system (due to backlash of the leadscrew and the gear reducer) can be represented by a normal distribution with standard deviation = ±0.05 mm. Specify the number of step angles that the motor must have in order to meet the accuracy requirement.arrow_forwardII. Provide complete solutions per problem. No need to copy the problem butprovide the ff format: (a) given (b) required (c)solution 2. A medium force fit on a 75 mm shaft requires a hole tolerance and shaft tolerance eachequal to 0.225 mm and average interference of 0.0375 mm. Find the hole and shaftdimensions.arrow_forwardComplete the hole specification including a position tolerance of .018" diameter at MMC relative to primary datum feature A, secondary datum feature B, and tertiary datum feature C.arrow_forward
