Two masses m1 and m2 are suspended from the ceiling by two string segments. What is the tension in each string segment? Let m1 = 10 kg and m2 = 20 kg.
To calculate the tension in each string segment, we can use the concept of equilibrium.
In this case, the tension in each string segment will be equal to the weight of the masses m1 and m2.
1. Calculate the weight of m1:
Weight = mass * gravity
Weight of m1 = m1 * 9.8 m/s^2
Substituting the given values:
Weight of m1 = 10 kg * 9.8 m/s^2
2. Calculate the weight of m2:
Weight of m2 = m2 * 9.8 m/s^2
Substituting the given values:
Weight of m2 = 20 kg * 9.8 m/s^2
Since the masses are suspended by two string segments, the total tension in the system would be equal to the sum of the weights of m1 and m2.
3. Calculate the total tension:
Total tension = Weight of m1 + Weight of m2
Substituting the calculated values:
Total tension = (10 kg * 9.8 m/s^2) + (20 kg * 9.8 m/s^2)
Simplifying, we get the value of total tension, which will be the same in each string segment.
To find the tension in each string segment, we need to consider the forces acting on each mass. In this case, we have two masses m1 and m2 suspended from the ceiling. The weight of each mass acts downward, while the tension in each string segment acts upward.
Let's start with m1. The weight of m1 can be calculated using the formula:
Weight1 = m1 * g,
where m1 is the mass of the first object and g is the acceleration due to gravity (approximately 9.8 m/s^2).
Weight1 = 10 kg * 9.8 m/s^2 = 98 N.
Since the mass is at rest, the sum of all forces acting on it must be zero. Therefore, the tension in the first string segment must balance the weight of m1. Let's call this tension T1.
T1 = Weight1 = 98 N.
Moving on to m2, we'll calculate its weight using the same formula:
Weight2 = m2 * g,
Weight2 = 20 kg * 9.8 m/s^2 = 196 N.
Again, since m2 is at rest, the sum of the forces acting on it must be zero. Thus, the tension in the second string segment (T2) must balance the weight of m2.
T2 = Weight2 = 196 N.
Therefore, the tension in each string segment is 98 N for m1 and 196 N for m2.
