The differential analyser , a mechanical analog pc designed to solve differential equations by integration , used wheel-and-disc mechanisms to perform the mixing. In 1876 Lord Kelvin had already mentioned the possible development of such calculators, but he had been stymied by the restricted output torque of the ball-and-disk integrators 14 In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Beginning in the 1920s, Vannevar Bush and others developed mechanical differential analyzers.
