Answer: Torque T = 40.7 Nm
Explanation:
Torque or turning effect is the rotational equivalent of linear force, i.e moment of force about a point.
Given that the force is applied perpendicular to the edge (angle 90°)
Torque can be represented by T;
T = FrSin∅ = Fr ( sin90 = 1)
T = force × distance
T = F × r
F = 55N
r = 74cm = 0.74m
T = 55N × 0.74m
T = 40.7 Nm
Answer:
It is a law of mechanics and physics discovered by Robert Hooke. This theory of elasticity says the extension of a spring is proportional to the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit.
Explanation:
When block is pushed upwards along the inclined plane
the net force applied on the block will be given as
here we know that
m = 75 kg
now plug in all values into this
now for finding the power is given as
Answer:
longitudinal wave
Explanation:
it is perpendicular to the direction of the wave
