block and tackle

The game of life is a lot like football. You have to tackle your problems, block your fears, and score your points when you get the opportunity.(人生的竞赛很像橄榄球赛，你必须解决你的问题，挡住你的恐惧，并在机会出现时得分。)

The drilling line is reeled over the crown block and traveling block to gain mechanical advantage in a "block and tackle" or "pulley" fashion.(钻井用钢丝绳通过天车和游动滑车以滑轮组的形式获得机械上效益。)

I finally hoisted him up with a block and tackle.(我最终用滑轮组把他拉了上去。)

When opening, carrying or installing it, please use block and tackle, chain block, fork lift truck or other assistant devices.(在开箱·搬运·安装时，请使用吊滑轮，起重机，叉式升运机等辅助设备。)

The problem about mechanical efficiency of tackle-block is the key point in junior high school mechanics and also the difficult point.(滑轮组机械效率问题是初中力学中的重点，也是初中力学解题的难点。)
