150 lbs is 150 pounds of draw weight, in a bow I would say that you'd need a brear of a person to wield it.
Fortunately, it is a crossbow you are talking about, but that is still too much for a child to draw.
Try using a bow with less draw weight and let them build up strength so they can use a stronger crossbow when they are older.
80 pounds is a very low draw weight for a crossbow and a very high draw weight for a standard bow
Nick weigh something like 141 pounds (64 kg) I guess.
Billy weigh something like 187 pounds (85 kg).
I guess that Joe weigh something like 140 pounds (64 kg) and Nick the same and Kevin 150 pounds (68 kg).
I guess that Trace weigh something about 141 pounds (64 kg). Because he is pretty skinny.

There are several exercises on the Weider Crossbow 2000x that will get you from 240 pounds down to 160 pounds. This includes the modified standing side bends, along with crunches and resistance based exercises.
Tensile strength is given in ksi. To get pounds you need to know the area. Pounds = strength x area. For example if the specimen is 100 ksi strength and area 1 sq inch, pounds = 100 x 1 = 100 kilopounds = 100000 pounds. f the specimen is 100 ksi strength and area 2 sq inch, pounds = 100 x 2 = 200 kilopounds = 200000 pounds. In any case strength in ksi is the same for a given material and that is why ksi is used.
Neither. Bolt tensile strength is in pounds per square inch. You are confusing torque with bolt strength. Typically a bolt will be torqued to stretch the bolt and preload it to about 50% of its strength. The relation between torque T and preload P is T = 0.15DP where D is bolt diameter(inch), T is inch pounds and P is pounds. Then stress is P/A where A is bolt area and this stress is 1/2 of strength. Note that torque in foot pounds is simply in lb/12, or 12 inch pounds = 1 ft lb
How do I convert foot pounds of torque to a tensile strength
It is the strength in pounds per square inch of a material at which it will be pulled apart.
A cats average strength is huge they can Carrie at least two pounds their weight.
