35 lb-ft (pound feet) equals about how many Nm (Newton meters) ? A. 45 B. 47 C. 50 D. 35

Answer is option: B i. e. 47N-m

1 pound-ft is the work done by an amount of force = 1 pound through the distance equal to 1 ft.

And, the conversion is:

1 N-m = 0.74 * lb-ft

Therefore, 35 lb-ft = (35/0.74) N-m

= 47N-m
