6. Write a user-defined MATLAB function that converts torque given in units of N-m to torque in units of lb-ft. For the function name and arguments, use lbft = NmTOlbft(Nm). The input argument Nm is the torque in N-m, and the output argument lbft is the torque in lb-ft (rounded to the nearest integer). Use the function to convert 2,000 N-m to units of lb-ft.
