In an interference force fit in a basic hole system, the
allowance is:
(a) zero
(b)negative
(c)positive
(d)greater than the tolerance of either the hole of the shaft
(e)equal to the nominal or basic dimension
Homework Answers
b) Negative
In interference fit, the dia of shaft is greater than the hole dia.
As such the allowance or the clearance is negative.
To fix the part pressure is
applied or the part is heated so as to expand and the rapidly
cooled back to its position.
These are used in fitting of rims, in car wheels, keypad pulley and shaft etc.
They are classified as Shrink Force Fit, Medium Force Fit and Tight Fit depending on the type of pressure applied.

V): It is usual practice to design a hub such that its outside diameter is about twice the bore diameter. It is also known that a selective assembly should be used when shrinking a hub on a shaft. The purpose of this problem is to determine how small and how large stresses can be with a shrink fit (class 8 fit) if a selective assembly is not used. As shown in Fig. 3, determine for a 2" diameter solid shaft,...

1. Is it possible for a system to have negative gravitational potential energy? a) Yes, as long as the kinetic energy is positive. b) Yes, as long as the total energy is positive. c) Yes, since the choice of zero of gravitational potential energy is arbitrary. d) No, because the kinetic energy of a system must equal its gravitational potential energy. e) No, because you can't have negative energy. 2.
