Find the mass m of the counterweight needed to balance the 1,923-kg truck on the incline shown as shown in the figure. Treat the pulleys as solid cylinders. The value of r is 1. The mass of the small pulley is M1 = 58 kg while the larger pulley is M2 = 137 kg. Ignore the mass of the pulley connected to the truck. Are the masses of the pulleys M1 and M2 needed in the calculation (answer this question to yourself only)? m 0 = 45° Note: final answer with zero decimal place.
