Tension Test Practice

Front

What is tension in physics?

Back

Tension is the force exerted by a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

How do you calculate the tension in a cable supporting a mass at an angle?

Back

Tension can be calculated using the formula T = (mg) / (2 * cos(θ)), where m is the mass, g is the acceleration due to gravity, and θ is the angle.

Front

What is the role of angles in tension calculations?

Back

Angles affect the distribution of forces; as the angle increases, the tension in the cable also increases for a given mass.

Front

If an object has a mass of 5.62 kg and is suspended at an angle of 60 degrees, what is the tension?

Back

The tension is 55.1 N.

Front

What is the tension in a cable when the mass is 5.62 kg and the angle is 45 degrees?

Back

The tension is 39.1 N.

Front

How does mass affect tension in a cable?

Back

As mass increases, the tension in the cable also increases, assuming the angle remains constant.

Front

What is the formula for calculating weight?

Back

Weight (W) is calculated using the formula W = mg, where m is mass and g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

If M = 22.1 kg and θ = 30 degrees, what is the tension in T1?

Back

The tension in T1 is 434 N.

Front

If M = 22.1 kg and θ = 30 degrees, what is the tension in T2?

Back

The tension in T2 is 376 N.

Front

What is the tension in a string supporting a mass of 12.7 kg?

Back

The tension is 125 N.
