A male standing erect can be 5â6 feet (1.5â1.8 m) tall and weigh 300â600 pounds (140â270 kg). According to the Guinness Book of World Records, the average male is 168 kg (370 lb) and stands upright at 163 cm (64 in). Males in captivity, however, are noted to be capable of reaching weights up to 275 kg. Females stand 5 feet (1.5 m) tall and weigh half as much as males. According to the late John Aspinall, a silverback gorilla in his prime has the physical strength of 7â8 Olympic weight lifters but this claim is unverified.
NP-3 | Nitrogen Plastic Welder. The Nitrogen Plastic Welder uses hot nitrogen gas to restructure common plastic components in automotive repair â from cracked bumper cover surfaces to hinged tabs. Nitrogen is used as a shielding gas to prevent the plastic from burning during the weld process â producing a strong, lasting weld.
Nitrogen is relatively cheap. A K size cylinder is less than $10.00 at most vendors. Air is about 79% nitrogen and 20% oxygen. When extracting oxygen for welding gas and medical use the water and other expensive gases are separated leaving dry nitrogen. Nitrogen has demand for dehydrating optical instruments and communication cables, but is still sold more on the basis of costs of inventory and transportation than on any intrinsic value.
