Solution to problem 17.1.2 from the collection of Kepe O.E.

Let's consider the problem:

Load weight m = 60 kg suspended on a thread that is wound on a drum rotating according to the equation ? = 0.6t². It is necessary to determine the rope tension if the radius r = 0.4 m.

To solve the problem, we use the formula for finding the rope tension:

T = m(r?2 + ?2)g,

Where g - acceleration of gravity, ? - angular acceleration of the drum.

Angular acceleration can be found by differentiating the drum rotation equation:

? = 1,2t

Substituting the known values ​​into the formula for rope tension, we get:

T = 60(0,4?2 + (1,2t)?2)9,8 = 588 + 7056t²

At t = 1 we get T = 7644 N = 617 (rounded to the nearest whole number).

Thus, the tension in the rope is 617 N.

Digital product "Solution to problem 17.1.2 from the collection of Kepe O.?." is a detailed description of the process of solving a physics problem. The problem considers a load weighing 60 kg, which is suspended on a thread wound on a drum rotating according to the law = 0.6t2. The task is to determine the rope tension for a drum radius r = 0.4 m.

The solution to the problem is based on the formula for finding the rope tension T = m(r^2 + ?^2)g, where g is the acceleration of free fall, and ? - angular acceleration of the drum, which can be found by differentiating the equation of drum rotation: ? = 1.2t.

Substituting the known values ​​into the formula, we get T = 60(0.4^2 + (1.2t)^2)9.8 = 588 + 7056t^2. At t = 1 we get T = 7644 N, which is rounded to the nearest whole number and equals 617 N.

The digital product contains not only the answer to the problem, but also a description of the solution process, the formulas used, and a beautiful html design that makes the reading process more fun. This product will be useful to students and teachers of physics, as well as to all lovers of popular science literature. The cost of the product is 99 rubles.

We present a unique digital product - the solution to problem 17.1.2 from the collection of physics problems from the author Kepe O.?. This product is ideal for physics students and teachers who are looking for a clear and understandable solution to a problem, as well as for all fans of popular science literature.

To solve the problem, it is necessary to determine the tension of the rope on which a load weighing 60 kg is suspended and which is wound on a drum with a radius of 0.4 m. The drum rotates according to the equation? = 0.6t2, where ? - angular acceleration of the drum, t - time.

To find the rope tension, use the formula T = m(r² + ?²)g, where g is the acceleration of gravity, ? - angular acceleration of the drum. Angular acceleration can be found by differentiating the drum rotation equation: ? = 1.2t.

Substituting the known values ​​into the formula for rope tension, we get: T = 60(0.4² + (1.2t)²)9.8 = 588 + 7056t².

At t = 1 we get T = 7644 N, which is rounded to the nearest whole number and equals 617. Thus, the tension in the rope is 617 N.
