A mass m = 5 kg is tied on one end of a rope and is forced to
execute a circle on a vertical plane so that
in completes one revolution every second. If the maximum tension
that the rope can withstand is 1000 N, find
the maximum length that the rope can have without breaking. Use g =
10 m/s2.

An athlete swings a 3.70 kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.970 m at an angular speed of 0.740 rev/s. (a) What is the tangential speed of the ball? m/s (b) What is its centripetal acceleration? m/s2 (c) If the maximum tension the rope can withstand before breaking is 115 N, what is the maximum tangential speed the ball can have? m/s

You are given a (massless) piece of string that is L=1.10 m long, and tied to the end of it is an object of mass m=5.40 kg. Like any string, it will rip if there is too much tension in it, and for this string that maximal amount of tension is T=104 N. a) If you held this string at one end and twirled it in a circle above your head, so that the object moves in a plane parallel...

A small rock with mass 0.50 kg is tied to the free end of a light string that is 8.0 m long. The rock is moving in a horizontal circle and the string makes an angle of 37° with respect to the vertical. a. What is the radius r of the circular path of the rock? b. What is the tension in the string? c. What is the period of the rock’s motion, the time it takes to complete one...

A puck of mass 0.678 kg is attached to the end of a cord 0.969m long. The puck moves in a horizontal circle without friction. If the cord can withstand a maximum tension of 132N, what is the highest frequency at which the puck can go around the circle without the cord breaking?
A string or rope will break apart if it is placed under too much tensile stress....
A string or rope will break apart if it is placed under too much tensile stress. Thicker ropes can withstand more tension without breaking because the thicker the rope, the greater the cross-sectional area and the smaller the stress. One type of steel has density 7780 kg/m3 and will break if the tensile stress exceeds 7.0×108N/m2. You want to make a guitar string from a mass of 3.9 g of this type of steel. In use, the guitar string must...

A uniform board of length 2.40 m and mass 4.00 kg is pivoted at
one end and has a rope attached at the other end, as shown in the
figure below. A bucket of mass 2.00 kg is suspended 40.0 cm from
the rope. Find: (a) the tension in the rope; (b) the horizontal and
vertical forces exerted by the pivot.

5) A mass m is connected to one end of a massless string of length L. The other end of the string is tied to a tall vertical pole of height H (much taller than L). The string is wound around the pole so that each wrap makes a small circle of the string and the mass touches the top of the pole. The mass is let go and the string begins to unwind. What is...
