The trade-off when the threads are closer together, is that more turns of the screw or bolt are needed to do the job because the distance over which the input force must be applied is greater. Having read the above passage, choose the right answer to the following question (choices are first bolt or second bolt ): If Jim is screwing in two bolts and the first one has threads that are close together while the second one has threads that are far apart, which one must he apply greater force to first bolt or second bolt?
first bolt
