GRADUALLY, SUDDENLY & IMPACT

LOAD MULTIPLE CHOICE QUESTIONS

(MCQ) WITH ANSWERS

MCQ on various types of forces make

the concept very clear. It increases the

depth of understanding too. Then, it

becomes easy to apply the basics in real

life applications. Gradually applied load

is increased  in equal instalments.

Suddenly applied load is applied in

one instalment. Impact load is due

to an impact. It involves motion.
