Step-by-step explanation:
Given : A weight of 18,000 lb is supported on a rectangular base plate that is 9 in. wide and 2 ft long. The base plate rests on a concrete slab.
To find : Determine the stress that the base plate exerts on the concrete slab. Express your answer in units of (a) lb/in². and (b) lb/ft².
Solution :
a) A rectangular base plate that is 9 in. wide and 2 ft long.
Converting ft into inches,
1 feet = 12 inch
2 feet = 2×12= 24 inch
The area of the rectangular base is
The weight is W=18,000 lb.
The stress that the base plate exerts on the concrete slab is given by,
b) A rectangular base plate that is 9 in. wide and 2 ft long.
Converting inches into ft,
1 inch =
9 feet =
The area of the rectangular base is
The weight is W=18,000 lb.
The stress that the base plate exerts on the concrete slab is given by,
