These losses are proportional to the square of the speed of the machine.<\/p>\n<ul>\n<li><strong>Current<\/strong> does not affect mechanical losses directly. However, current can affect mechanical losses indirectly by causing heating of the machine&#8217;s windings. This heating can cause the windings to expand, which can increase friction and windage losses.<\/li>\n<li><strong>Voltage<\/strong> does not affect mechanical losses directly. However, voltage can affect mechanical losses indirectly by causing the machine to draw more current. This increased current can cause the machine to heat up, which can increase friction and windage losses.<\/li>\n<li><strong>None of the above<\/strong> is not the correct answer.
