Unit of pressure in SI unit is ________.
N / m
m / N2
N / m2
m / N
Turning effect of force is ________.
torque
moment of force
balancing moment
couple
Moment can be calculated using the equation:
M = F × d
M = F / d
M = F2 × d
M = F / d2
One Pascal is the pressure generated by ___________.
force of 1 N on an area of 1 m2
force of 1 kgf on an area of 1 m2
force of 1 N on an area of 1000 m2
force of 1 N on an area of 1 cm2
Formula for calculating Pressure is:
Pressure = Thrust / Area
Pressure = Thrust × distance
Pressure = Thrust × distance
Pressure = Area / Thrust
Two boys exert force of 40 N and 60 N in opposite directions on an object. The magnitude of the resultant force is ________.
20 N
200 N
40 N
240 N
A force of 1200 N acts on a surface of area 10 cm2 normally. What would be the thrust and pressure on the surface?
12 × 106 N/m2
2 × 106 N/m2
1.2 × 106 N/m2
1.2 × 104 N/m2
Calculate the pressure produced by a force of 800 N acting on an area of 2.0 m2.
400 Pa
800 Pa
40 Pa
None of these
The moment of a force causes an object to
move forward.
move backward.
stop moving.
turn about a fixed point
1. An elephant weighing 20,000 N stands on one foot of area 1000 cm2. How much pressure would it exert on the ground?
2,00 N/m2.
2,00,000 N/m2.
2,00,00 N/m2
2,00,0 N/m2.
1. With increase in the area of contact of an object, the pressure
increases.
decreases.
is not affected.
turns about a fixed point.
With increase in the weight of an object, the pressure
increases.
decreases.
is not affected.
turns about a fixed point.
Watch the green man. Which force(s) are acting in this situation?
Frictional Force only.
Gravitational Force only.
Muscular Force only.
Muscular and Gravitational Force.
Watch the tyres of tractor rolling. Rear tyres are broader because
It looks good.
Broader tyres lessen the muscular Force required.
Broader tyres lessen the pressure on ground.
Broader tyres lessen the friction on ground.
Which sentence is the MOST RIGHT fit for this image?
Flat shoes are better than heels.
Pressure distribution is less for flat shoes.
In muddy area, it's not a good idea to wear heels.
Less the area, less is the pressure. So heels create less pressure.
If the Pressure is 50 Pa, and area is 5 cm² Find thrust.
10N
250N
20N
25N
measure of the gravitational force acting on an object
gravity
balanced force
unbalanced force
weight
force
