Mechanics and Simple Machines

Vocabulary flashcards covering mechanics, including momentum impacts, hydraulic press systems, and inclined planes based on student lecture notes.

Impulse force

The force calculated for a car of $1600\,kg$ zavelling at a velocity of $Mods$ when the impact takes $2\,second$.

Hydraulic press system

A system using a lover of negligible mase with a piston pivoted of point P, featuring Piston A with an Area of $30\,cm$ and Piston B with an Area of $360$.

Velocity Ratio (VR)

A property of the hydraulic press system determined using the areas of Piston A ($30\,cm$) and Piston B ($360$).

Mechanical Advantage (MA)

The ratio of the load force to the effort force, which is calculated for the machine systems.

Efficiency

The ratio of MA to VR, given as $80\%$ for an inclined plane lifting a load through a vertical height of $4.0\,m$.

Inclined plane

A simple machine that makes an angle of $300$ with the horizontal, used to lift a $50\,kg$ load through a vertical height of $4.0\,m$.

Work done against friction

The energy lost while raising a $50\,kg$ load through a height of $4.0\,m$ at a constant velocity, calculated with $g = 10\,N/kg$.

Effort

The force applied to move a load, such as the $100\,N$ force applied to the lever or the force required to move a load up the inclined plane.
