4.3 Review Assignment tolerance and fits Brendon Richardson

In a limit system, the following limits are specified for a hole and shaft assembly: Hole = 70 (+0.04 )/(+0.00 ) mm and Shaft = 70 (-0.04)/(-0.08) mm. Determine the basic size, tolerance and allowance, maximum and minimum clearances, type of fit.

Complete 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.

Calculate the dimensions of shaft and hole for assembly condition specified asø50H7/d9. Identify condition of fit and calculate allowances. Use tolerance grade chart frombook/PPT

Please answer number 5-8

5. If the pin in the figure below were produced at a diameter of 1.004 and toleranced with the feature control frame in Fig. 6-16, what would the total perpendicularity tolerance be? A O 1.010 O .008 .010 O .004 01.000-1.010 0.002MA 2.00

Please answer and show working out please and label each part

Q-3     Three blocks A, B, and C and a grooved block D have dimensions a, b, c, and d as follows: a = 40.500  0.025 mm               b =   52.000  0.075 mm c = 73.000  0.015 mm                d = 165.900  0.250 mm  Parts A, B, and C are standard parts supplied by vendors from the market, but  we are to machine part D according to the the width that you are asked to specify.                                                (a) Determine the mean gap w0 of w and its tolerance.                               (b) Determine the mean size of d (d0) that will assure that w ≥ 0.050 mm.

Q.2 Design a Jig to drill2 holes of 10 mm diameter and a single hole of 10 mm diameter. Refer design data book for designing various parts of jig and mention values referred from design data book. DRILL DRILL O I0 ø 10 2x 4 PIN 25 50 FIG 12 50 SHN $25 20.0 - O 75 25 25 CTS CTS

In gear designs, geometric numbers, I and J will be needed to calculate bending and contact stress numbers per per AGMA standards. Please select all the answers that apply.     Geometry factor I will be different for the pinion and for the gear.      Geometry factor J will be the same value for both the pinion and for the gear.      Geometry factor J will be the different for the pinion and for the gear.      Geometry factor I will be the same value for both the pinion and for the gear.

Statics Problem !!! Help me part D!!!! Answer it this Problem Correctly!! Please give correct Solution

II. Provide complete solutions per problem. No need to copy the problem butprovide the ff format: (a) given (b) required (c)solution 1. A journal of basic size of 75 mm rotates in a bearing. The tolerance for both the shaftand bearing is 0.075 mm and the required allowance is 0.10 mm. Find the dimensions ofthe shaft and the bearing bore. 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.

Please solve all questions please this one is much urgent please please please

Please give the right solution other wise skip to another expert. Calculate the fundamental deviation and tolerances and hence the limits of size for the shaft and hole for the following fit: 60 mm H8-f7. The diameter steps are 50 mm and 80 mm.

Please provide the given, step by step manual solution, units, and drawing for below given Machine Elements II problem.    It is generally recommended and normal for a designer to add a hunting tooth to evenly distribute the wear on meshing teeth like a 53 teeth mesh with 30 teeth pinion. Find the rotation of pinion to mesh same pair of teeth again.

15.)A full journal bearing has a journal diameter of 4.000in. with a unilateral tolerance of -0.004in. The bushing bore has a diameter of 4.004in and unilateral tolerance of +0.004in. the bearing is 3in long. The journal load is 3000 lbf and it runs at a speed of 400 rpm. What is the load per projected bearing area 9P) in psi? Choose answer below 75 100 125 250 16.)For the bearing in problem #15, if the lubricant average viscosity is 9 ureym, what is the Sommerfield number (assuming minimum clearance) Choose answer below Between 0.6 and 0.7 Between 0.5 and 0.6 Between 0.3 and 0.4 Between 0.2 and 0.3
