What is the maximum pressure a concrete block measuring 0.5m x 1m x 2m which has a weight of 26000 newtons can exert on the ground?

big pressure comes from smaller surface areas therefore we need to find a side of the block with the smallest surface area. if you do 1m x 2m, that equals 2m squared and that is a large surface area. if you do 2m x 0.5, that equals 1m squared and that is STILL not small enough. HOWEVER if you do 0.5 x 1, that equals 0.5m squared and that is perfectly small enough.
since pressure=force divided by area, we have to do 26000 (which is the force) divided by 0.5m squared which becomes 52000. therefore the final answer is 52,000 pascals.

What is pressure force?
Pressure is defined as the following Pressure = force / area. So what this means is pressure is how much force is exerted over a area of given size. For examle a concrete slab is on the floor this slab has a width of 2m and a length of 2 m its area is 2 x 2 which gives 2m Squared. Its force it exerts is 1000 newtons ok what the hell does this mean? if you place this in the formula you will get pressure = 1000/4 Pressure = 250 newtons per square metre. I hope this answers you question on what pressure is.
What is force in newtons divided by the area?
Force divided by area is pressure. If the force is in newtons and the area is in metres squared, the pressure will be in pascals (Pa).
What pressure expressed in pascals equals 70 newtons per meters squared?
70Pa
What is the metric unit of measure for barometer?
A barometer measures pressure, and the SI unit for pressure is the Pascal, equivalent to Newtons / square meter.
Would you weight a students desk in grams or kilograms?
Neither. Both gram and kilograms are units for measuring mass, not weight. The weight would be measured in Newtons.
What is the force in newtons exerted on a surface measuring 0.25 m2 if the pressure is 101 Pa?
Pressure = Force per unit area = Force/area Therefore the force is equal to the pressure*the area. Force = pressure*area = 101*0.25 = 25.25 Newtons
A barometer is an instrument used for measuring water pressure?
otherwise know as a barometer and it measures air pressure in newtons
What is use measuring pressure?
Newtons ------------------------------------------------------- The unit of pressure in the SI is pascal (Pa). Pascal is defined as N/m2; 1 technical atmosphere(at) is 9,80655.10e4 pascals.
A concrete column has a volume of 565 m cubed and a height of 20 m What is the maximum weight expressed in newtons that the column can tolerate before fracturing?

How are newtons and centimeters squared related?
Pressure = force (newtons) / area (sq. cms)units are newtons per sq. cmNote: SI units for pressure are newtons / sq. metre (pascals)
What is th si unit for measuring force?
Newtons or kilonewtons.
Why do we use Newtons?
Newtons is a unit of measuring force and is not to be confused with measuring mass. Another unit of measuring force is pounds. Newtons are often used as they are the SI unit of force.
What are the units for measuring forces?
In the SI system, newtons. In the English System, pounds. Hope this helps!
What is C-40 grade of concrete used for?
Constructions that require the concrete to withstand 40 Newtons of compressive force.
What is the equivalent of 3000000 Pa in newtons?
The pressure measured in pascals means the force in newtons per area in square meters. Pascals cannot converted to newtons, because the area is missing. Pascals means pressure and newtons means force.
