What happens when tension is less than weight?
mass x acceleration = tension – weight If the acceleration is a= m/s2 then a net force= Newtons is required to accelerate the mass. Note that the tension is equal to the weight only if the acceleration is zero, and that if the acceleration is negative (downward), the tension is less than the weight.
How much force does it take to break a rope?
The required safety margin breaking strength = (20)(980 kN) = 19600 kN. The breaking strength of a cable depends directly on its cross sectional area….Breaking Strength of a Cable.
Material | Breaking Strength (kN) 12.5 mm (1/2 inch) diameter | Mass (g/m) |
---|---|---|
Stainless steel | 95 | 3000 |
Kevlar | 65 | 60 |
Nylon rock climbing rope | 40 | 100 |
How does a rope break?
So, rope can be broken by the tension in the rope. Note that T is not equal to 2F. The equal forces applied on both sides of the rope adds to the tensile force bearing on it. Until that added force exceeds the elastic limit of the rope, could it sustain its shape further it would be broken.
Does tension depend on weight?
Does Tension Depend on Mass? If weight is hanged from a cable or wire from a fixed point, the wire or cable would be under tension proportional to the mass of the object. The wire is under tension proportional to the force of pulling.
Can tension be more than weight?
I’m assuming you are asking to compare tension (which is a force) to the gravitational force exerted on the mass on the end of the string. If that’s the case, then yes, the tension can be either greater or less than the gravitational force on the mass.
Is the tension in the string greater than?
the weight force (W) , of the ball, is in the downward direction, the tension force (T) on the ball is in the upward direction and the centripetal force (F) is also in the upward direction. Thus, the tension in the string is greater than the ball’s weight.
Can tension ever be greater than weight?
How much weight can a rope support?
For instance, both single and twin rope types must have an impact force of 12kN. It means that you can carry a maximum weight of 2,646 pounds (1,200 kilograms). On the other hand, half ropes must come with a maximum impact force of 8kN for a maximum payload of 1,764 pounds (800 kilograms).
Does a rope break?
Ropes don’t BREAK! Ropes don’t break by overload, but they do by cutting and abrasion – so take care, not all landings are this forgiving!
Does more tension mean more likely to break?
tension is greatest at the bottom of the circular path. This is where the rope is most likely to break. As long as the ball moves faster than “the square root of GRRRRRRRR”, then the ball will complete the circular loop.
