And not only did the Martians either not know of (which is incredible), or abstain from, the wheel, but in their apparatus singularly little use is made of the fixed pivot or relatively fixed pivot, with circular motions thereabout confined to one plane.
Due to their parallel kinematics design (Figure 5) there is only one moving optic with a fixed pivot point, leading to reduced inertia and higher dynamics in a smaller package, while achieving superior accuracy.
On underwater turning movement, the turtle pivoted its body, using the inboard hindlimb as a fixed pivot point.
During underwater turning the inboard hindlimb is used as a fixed pivot point, and the other limbs are used to produce a turning movement, following the stride stages for a straight line movement described by Walker (1971).
It is also assumed that the driving link has a fixed pivot and therefore the system of forces and couples is diminished to a single reduced couple, which acts instead of the set of external loads.
Driving link with fixed pivot. Figure 3.b presents a driving link with fixed pivot.
It is also supposed that the driving link has a fixed pivot and therefore the set of inertial parameters is diminished to a single reduced moment of inertia [] which represents the dyad.
The mainframe, loading gate, and hammer are all color case hardened by Turnbull, and the specially designed pawl rides on a fixed pivot and is expected to have three to four times a life expectancy of other traditional pawl springs.
"From the information we have at the moment, the front of the bus was like a fixed pivot, with the rear of the bus spinning around and eventually ending up in the ditch.
Individually they pose a threat to the Irish back-row and half-backs and it is disturbing that O'Sullivan was unable to settle on a fixed pivot unit - back-row, scrum-half and out-half - by this stage in the competition.
When short relocations are required at the face, the units function as a simple lever mechanism and follow the movements of the Lokotrack around the fixed pivot point on its discharge conveyor.
To allow vertical positioning of the light, the suspension must rotate about a fixed pivot. The combined weight f the suspension components and light produces an applied moment about the fixed pivot thta varies as a function of the angle of rotation (see Figure 2).
