A hydraulic press has a large circular piston of radius 0.8m and circular plunger of radius 0.1m . A force of 200N is exerted by a plunger . Find the force exerted on the piston

Explanation:

Let's use the Pascal principle:

Where:

F(i) is the input force, 200 N

F(o) is force exerted on the piston  

A(i) is the area of the plunger (A =πr(i)²)

A(o) is the area of the piston (A =πr(o)²)

volts times amps 6 x 0.5 3w

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
