Question

find M.

Problem No. 2Joints of machine elements. Calculations on strength Different types of joints of machine elements are shown in Figure 9 such sleeve is attached to the shaft with the aid of cylindrical pin with diameter d. In all variants allowable stresses for material of elements to be jointed, for rivets and pins are considered as follows: [o]-150 MPa. [σ -250 MPa and [τ-100 MPa. Allowable stress for material of weld is equal to [1-80 MPa. It is necessary to determine parameter which is labeled in the table with question symbol. b80mm

Answer 1

Answer

M = $(\frac{\tau * J}{r})$ = = 100 Kn.m

100 106 4.021 40

J =
π* 3
=
π * 0,084
= 4.021 m⁴
