Answer:
Mass of the pull is 77 kg
Explanation:
Here we have for
Since the rope moves along with pulley, we have
For the first block we have
T₁ - m₁g = -m₁a = -m₁g/4
T₁ = 3/4(m₁g) = 323.4 N
Similarly, as the acceleration of the second block is the same as the first block but in opposite direction, we have
T₂ - m₂g = m₂a = m₂g/4
T₂ = 5/4(m₂g) = 134.75 N
T₂r - T₁r = I·∝ = 0.5·M·r²(-α/r)
∴ [tex]M = -\frac{2}{a} (T_2-T_1)[/tex]
[tex]M = -\frac{2}{2.45} (134.75-323.4) = 77 \, kg[/tex]
Mass of the pull = 77 kg.
The Mass of the pulley is 77 kg. A tension is a force along the length of a medium, especially a force carried by a flexible medium, such as a rope or cable.
What is Tension?
Tension is a force that works in medium lengths, especially those that are flexible, such as rope or cord. Tension force remains a gravitational force.
Since, the rope moves along with pulley, we have
For the first block we have
T₁ - m₁g = -m₁a = -m₁g/4
T₁ = 3/4(m₁g) = 323.4 N
Similarly, as the acceleration of the second block is the same as the first block but in opposite direction, we have
T₂ - m₂g = m₂a = m₂g/4
T₂ = 5/4(m₂g) = 134.75 N
T₂r - T₁r = I·∝ = 0.5·M·r²(-α/r)
Therefore, Mass of the pull = 77 kg
