A helicopter flies over the arctic ice pack at a constant altitude, towing an airborne 129-kg laser sensor that measures the thi
ckness of the ice (see the drawing). The helicopter and the sensor both move only in the horizontal direction and have a horizontal acceleration of magnitude 2.84 m/s2 . Ignoring air resistance, find the tension in the cable towing the sensor.
1 answer:
Answer:
1317.52 Newton
Explanation:
Mass of sensor = m = 129 kg
Acceleration of the sensor = a = 2.84 m/s²
g = Acceleration due to gravity = 9.81 m/s²
= Force on the laser sensor due to motion = 129×2.84 = 366.36 N
= Force due to gravity on the laser = mg = 129×9.81 = 1265.49 N
Tension in the cable
∴ The tension in the cable towing the sensor is 1317.52 Newton

Explanation :
Simple machines makes our work easier. Lever is one of the simple machine which consists of rigid rod that is pivoted at a fixed support called as Fulcrum.
There are three classes of lever.
Class 1 : In this type of class, fulcrum is placed in between effort and load. Hence the movement of load is in reverse direction of the movement of effort. (fig 1)
Class 2 : In this type of, the load is between the effort and the fulcrum. Hence, the movement of load is in same direction as that of the effort. (fig 2)
Class 3 : In this type of lever the effort between the load and the fulcrum. Hence, both the effort and load are in same direction. (fig 3)
Hence, when the position of fulcrum is modified the effort force changes.
