A stone pillar has a mass of 3.0 tonnes, if the area of its base is 0.3m2, calculate the pressure under the pillar.

P = 98100 [N/m2]

Explanation:

To solve this problem we must use the following mathematical expression, which tells us that pressure is the relationship between Force and area.

P = F/A

where:

P = pressure [N/m2]

F = force [N]

A = area [m2]

We must convert the mass from tons to kilograms.

m = 3 [ton] * 1000 [kg/1 *ton] = 3000 [kg]

Force is defined as the product of mass by gravity.

F = 3000*9.81 = 29430 [N]

P = (29430/0.3)

P = 98100 [N/m2]

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

the higher the current the higher the mag field around it the higher the influence on the compass
