A car weighing 13,000 N starts from rest and accelerates to 95.0 km/h in 5.00 s. The friction force is 1,450 N. Find the applied force (in N) produced by the engine. (Enter the magnitude.)

Abeam has a square cross-section, a x a, where a is the linear dimension, and is subject to a pure bending moment, m. m is known with an uncertainty of 10% and a is known with an uncertainty of 5%. the strength of the material is known to an uncertainty of 12%. find the minimum design factor such that the beam is guaranteed not to fail.
