Tension is maintained in a string by attaching one end to a wall and by hanging a 2.34 kg object from the other end of the string after it passes over a pulley that is 2.00 m from the wall. The string has a mass per unit length of 3.45 mg/m. What is the fundamental frequency ...

the force diagram reflects the physical setup the walker is 15.0 m from either end; and is displacing the wire 1.0 m this means that the vertical component of the tension is one-fifteenth the tension in the wire (on BOTH sides) so the force exerted by the walker is 3675/15 * 2...

arcsin 3.8/22 = 9.95 degrees is the sag angle. So far, so good. 2 T sin 9.95 = M g = 549 N That is the vertical force balance equation. T is the tension on either side of the tightrope walker. T = 549/[2*0.173) = 1590 N <<Is it possible to increase the tension in...

In anticipation of part B I am going to take moments about the cable A attachment I will do it all in Kg instead of Newtons because g will cancel except at the end. m positive down cable A x = 0 m = A Man x = 1.5 m = 75 beam x = 4 m = 68.8 cable B x = 6 m = B cat x = 8 m = 3.5...

Two blocks are connected by a string over a frictionless, massless pulley such that one is resting on an inclined plane and the other is hanging over the top edge of the plane. the hanging block has a mass of 16 kg and the one on the plane has a mass of 8 kg. the coefficient ...

a uniform beam of weight 420 N and length 3.2 m is suspended horizontally. On the left it is hinged to a wall; on the right is it supported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1200 N. (a) What value of D ...

Take the angle of sag. if Then x/12.5 =tan Sagangle. But look at force. The downward force is 1/2 75g (each side holds half the weight) so 37.5g/Tension=Sin Sagangle But the tension cannot be greater than 27kN/12 so you can then determine the sag angle. Put that back in to the...
