Mathematics of the Slider Cranks

3. Offset Slider Cranks: C04, D01

There are many variations of the slider crank. The
most
common is to have the slider *B* constrained to move along a
straight line
that does not contain *C*. This is called the *off-set slider
crank*.
See the following two figures of **C04** and **D01**.

**C04**

D01

Now, similar to analysis in 1.
Generic Slider Crank before, we
obtain:
, where *d* = *DD’* is the
distance
of *C* from the straight line constraint for the slider.

Also, notice that (***) .

By the Pythagorean Theorem, . Thus,

(****) .

The offset slider crank can have the same four inversions depending on which part of the mechanism is held fixed.

1. Generic
Slider Crank (**C02**)

2. Inversions
of the Slider Crank (**C02**, **C05**, **D2**)

4. Topological
Extensions of the Slider Crank (**D14**, **D07**, **D08**,
**C06**)
