Humble Life safety Opinion On Horizontal Forces:

Most guys today never experience seeing a (4) legged horse trying to stand up, fighting Hurricane force winds ..... in any case, just imagine him trying to stand up on his thin (3) legs.

When under a vehicle, (with wind or no wind), picture the very strong sideways forces exerted in trying to unscrew a heavily rusted bolt or nut with a socket attached to a long cheater bar .......... and then think about the horizontal resistance to horizontal forces with a (4) legged horse & a (3) legged horse .... and how about resistance offered with a (4) legged jack compared to a (3) legged jack.

If the (3) legged horse tumbles over, he gets back up ...... if a (3) legged jack stand tumbles under a heavy iron crushing vehicle ... you could very possibly win a short ride in an ambulance or in a hearse.

Hope this helps to decide.
