A weight is suspended from the middle of a rope whose ends are at the same level. the rope is no longer horizontal. the minimum tension required to completely straighten the rope is

A rigid mass less rod of length L is hinged at its  one end and a weight W is hung at a distance l(<L) from this end. What a force P should be applied upwards at the other end so that the rod remains in equilibrium horizontally ?

A 35.0 kg girl swings on a swingset.  At the bottom of the swing’s path, she feels as though she weighs 435 N.  What is the value of the tension in the swing’s ropes at the bottom of the swing’s path?

A lift with a mass 1200 kg is raised from rest by a cable with a tension 1350 kg-f. After some time thetension drops to 1000 kg-f and the lift comes to rest at a height of 25 m above its initial point.

A uniform, horizontal beam of length 6.0 m and weight 140 N is attached at one end to a wall by a pin connection (so that it may rotate). A cable attached to the wall above the pin supports the opposite end. The cable makes an angle of 60° with the horizontal. What is the tension in the cable needed to maintain the beam in equilibrium?Select one:a.81 Nb.140 Nc.70 Nd.69 N

A rod is pivoted around its left end and is supported by a rope that is attached some distance above the pivot point. A mass is placed 61.2 cm to the right of the pivot pointFind the tension in the rope when the mass is in the position shown in the picture to the left
