# Solution to Problem 456 | Moving Loads

**Problem 456**

Three wheel loads roll as a unit across a 44-ft span. The loads are P_{1} = 4000 lb and P_{2} = 8000 lb separated by 9 ft, and P_{3} = 6000 lb at 18 ft from P_{2}. Determine the maximum moment and maximum shear in the simply supported span.

# Solution to Problem 455 | Moving Loads

**Problem 455**

A tractor weighing 3000 lb, with a wheel base of 9 ft, carries 1800 lb of its load on the rear wheels. Compute the maximum moment and maximum shear when crossing a 14 ft-span.
