The simple machines are the operations that allows the easy in the completion of work. The Julian toes to reach book act as fulcrum.

<h3>How do simple machine works?</h3>

The operation of work done is performed with the completion of task after the application of force. The force act at different parts of the simple machine allows the ease in the work done.

The toes of Juliana in reaching to the book allows her to apply force to them, and they help to leverage Juliana weight to the height. The mechanism is being carried by a simple machine fulcrum.

Thus, the toes of Juliana act as fulcrum by helping her in reaching to the book.

When comparing the two chair conformations for a monosubstituted cyclohexane ring, which type of substituent shows the greatest

Klio2033 [76]

Large substituents will chose equatorial conformation over axial conformation more readily.

<h3><u>Explanation</u>:</h3>

The axial conformation of the monosubstituted cyclohexane molecule is the Conformation where the substituted group is located along the axis of the molecule, perpendicular to the plane of the molecule. The equatorial conformation on the other hand is the substituted group being aligned along the plane of the molecule.

Now, in the axial position, the large groups will face steric hindrance with the axial hydrogens of the other carbon atoms which will lead the molecule more unstable. So larger is the group, more is the steric hindrance. So larger group will prefer the equatorial conformation more readily than the axial conformation.
