The definition of torque alows to find the force of the engine of a truck is 257.5 N
Torque is the vectorial product of force and distance,
τ = F x r
The bold letters indicate vectors, τ is the torque, F the force and r the distance
The magnitude of this expression is
τ = F r sin θ
In trucks the distance from the motorcycle to the pivot point on the rear wheels is approximately 2 m and the angle between the force and the wheel axis is 90º
F =
Indicate that the torque is 515 N m, let's calculate
F = 515/2
F = 257.5 N
In conclusion, using the definition of torque we can find the force of a truck engine is 257.5 N

Answer:
The mirror is opaque while the lens is transparent
Explanation:
The lens is transparent throughout (lets light pass through), while the mirror reflects light. You are basically asking for the difference between a lens and a mirror
But how about the the behaviors of the convex mirror and convex lens? The convex lens will let light pass through and focus it on the other side of it. If you stand on one side of the lens, you can see what is on the other side of it. Think about a camera lens that's just curved!The convex mirror will reflect the light on the same side of it you'll basically will just see yourself but you'll look funny.
