APPLIED STATICS AND STRENGTH OF
MATERIALS FINAL PAPER 2026 COMPLETE
PROBLEMS AND DETAILED ANSWERS GRADED
A+
◉ Hooke's law does not apply when the material being tested goes into
the plastic range. Answer: true
◉ For a long slender column, critical load is the load at which the
column is crushed. Answer: false
◉ Leonhard Euler is credited with the development of the equation for
calculating the modulus of elasticity. Answer: False
◉ For steel columns, the slenderness ratio should not exceed 200.
Answer: true
◉ According to Hooke's law, deformations are directly proportional to
stresses within the elastic range. Answer: true
, ◉ The moment of inertia for a square beam cross section of 6"x6" would
be 108 in4. Answer: true
◉ For a wooden column, the slenderness ratio is calculated as 63. This
column is safe to be used because it is below the recommended guide.
Answer: false
◉ Buckling usually happens at a stress level that is less than the yield
stress of a column. Answer: true
◉ Yield stress for a square steel column 2"x2" is given as 36000 psi.
Maximum load Pmax will be 72 tons. Answer: true
◉ Critical load Pcr on a column is calculated by the Euler's equation. If
the actual load on a column exceeds Pcr, the column is subject to
buckling. Answer: true
◉ President Abraham Lincoln was responsible for initiating the
Interstate Highway system in the United States. Answer: false
◉ Stress is calculated by dividing the Force or load by the cross
sectional area. Answer: true
◉ A wooden beam section has a width of 4 inches and a depth of 5
inches. Its cross sectional area would be 9 square inches. Answer: false
