5. Under normal circumstances, a safety helmet can withstand the impact of a ( ) kg hammer falling from a height of 1 meter. A, 2 ； B, 3 ； C, 4 ； D, 5: I referred to the post from this forum’s Production Technology Exchange section titled “Training Manual for Chemical Process Control Operator Skill Assessment”, dated 2008-7-31. It seems that B should be the correct answer; indeed, I’ve learned a lot from this forum.

In my opinion, the impact resistance is 5KG, and the puncture resistance is 3KG
Reply #32009-09-22
The ultimate impact force is 5, but it might be broken even if a local force of 5 kilograms is applied!
Reply #42009-09-25
Hammers are generally specified in terms of pounds; hammers measured in kilograms are not available on the market

5Kg, upstairs. This is a test question; there’s no need to get too worried about the units used~~
