Question

machine parts are jammed in cold days why?​

Answer 1

1) Due to the low temperature in winter, the coefficient of viscosity of the engine oil and the lubricant increases. The machine parts get jammed due to this reason. 2) Static friction comes into play when the horse applies force to start the motion in the cart.
