3. A 1.29 kg ball is connected by means of two ideal strings to a horizontal, rotating rod. The strings are tied to the rod and are taut. The right string is 26.0 cm long and has a tension of 29.3 N, and it makes an angle 02 = 50.0° with the rod, while the left string makes an angle 01 = 64.0° angle with the rod. At the instant shown the ball is at its highest point. (a) What...

1. A mass of 4.00 kg is supported in the X-Y plane by two strings. String 1 pulls up and to the left. String 2 pulls up and to the right. Both strings are attached to the ceiling. String 1 makes an angle of 40.0 degrees with the ceiling. The tension on string 1 is 35.0 N. a) Draw the free body diagram of the mass and two strings. b) What is the magnitude of the X component of the...

An unknown mass is held motionless supported by a string tied in a knot that is connected to two other strings as shown in Figure 3. One string (labelled as Ti in the figure) has a tension of 120 N and makes a 22o angle with respect to the ceiling. The tension in the other string is unknown but it makes a 38 angle with respect to a line perpendicular to the ceiling. If we assume all strings are massless...

A 7.00-kg block is attached to a vertical rod by two strings, each of which has a length of 1.30-m, and attached to the center of the block’s face closest to the vertical rod. The strings are attached 2.25-m apart on the vertical rod, and the system rotates about the axis of the vertical rod. Sketch a real world picture of this scenario. Show how to determine the rpm at which the lower string goes slack. Show how to determine...
