4. A multimeter having a sensitivity of 4,000 2/V is used to measure the voltage across a circuit having an output resistance of 20k92. The open-
circuit voltage of the circuit is 7.5 V. Find the reading of the multimeter
when it is set to its 10 V scale. Also find the percentage error.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
