Is there a way to turn this tensile strength into maximum tension which is in Newtons?

I've honestly never heard of tensile strength before.
Is there a way to turn this tensile strength into maximum tension which is in Newtons?
crimsonn said:So it's a quantity somewhat like Tension?
Is there a way to convert this into Newtons?
I don't know if it's possible because this is lbs/cm2 but Newtons are kg/m * s2
crimsonn said:I know! I'm sorry the calculation was off (i fixed it). I just wanted to convert the answer into meters...or something (it's dumb mistakes like that that really get to me)
so, the length of the rope doesn't matter. Thanks!
.2 * 20,000lbs^cm2 would be 4000lbs.
How does this factor back into centripetal force? Fc= mv^2/r say at a rate of 15m/s and his web is shooting off 30m and he's swinging across traffic.
The centripetal force would have to be less than what the rope could hold. Correct? Either that, or spiderman would have to swing at a faster rate.
(I know I'm asking a lot of questions. I really appreciate everyone who's helping!)
crimsonn said:Wow. Now I'm very confused. Well, that or overwhelmed with the amount of information I need to know. Summary so far.
The radius of his spider silk is crucial to determining the maximum amount of weight this string can hold. But then, how much will this silk weigh?
For spiderman and Mary-Jane to get across safely their combined weight has to be less than the the maximum weight the rope can hold. And The tension of the rope has to be more than the centripetal force?
Is this correct?
crimsonn said:So,
Fc + mg = T
this T has to be less than the value I am given.
But my answer for T will be in Newtons, so how do I compare this to 20,000lb/cm^2?
Google said:1 Newton = 0.224808943 pounds force
crimsonn said:The last piece of info:
what do you think is a reasonable diameter for a silk strand. I understand it's going to be pretty small. But then again, spider silk is very strong
Tensile strength is the maximum amount of stress that a material can withstand before breaking or rupturing. It is a measure of a material's ability to resist tension forces.
Tensile strength is typically measured through a tensile test, where a sample of the material is subjected to increasing amounts of tension until it breaks. The maximum amount of tension the material can withstand before breaking is recorded as its tensile strength.
Tensile strength can be affected by a variety of factors, including the composition and structure of the material, temperature, and the speed at which tension is applied. For example, materials with impurities or defects may have lower tensile strength, and higher temperatures can cause a decrease in tensile strength.
Tensile strength and yield strength are two measures of a material's strength, but they represent different properties. Tensile strength is the maximum stress a material can withstand before breaking, while yield strength is the stress at which a material begins to deform permanently. In other words, yield strength is the point at which a material experiences a permanent change in shape, while tensile strength is the point at which it breaks.
Tensile strength is an important property in material science because it helps determine a material's suitability for different applications. Materials with high tensile strength are often used in structures and machinery where they will be subjected to large amounts of tension, while materials with lower tensile strength may be better suited for other purposes. Understanding the tensile strength of a material can also help predict its behavior in different environments and under different conditions.
