Statics
Physics ⇒ Mechanics
Statics starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Statics.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Define the term 'center of mass'.
Describe the principle of transmissibility of forces.
Describe the role of friction in maintaining static equilibrium.
Explain the difference between stable, unstable, and neutral equilibrium with examples.
A 2 m long uniform bar is supported at its midpoint. If a 10 N weight is hung 0.5 m from one end, where should a 20 N weight be hung on the other side to balance the bar?
A 3 m long uniform rod of mass 6 kg is supported at one end. What is the moment of force required at the other end to keep it horizontal? (Take g = 10 m/s²)
A 50 kg sign is suspended by two cables making angles of 30° and 60° with the horizontal. Calculate the tension in each cable. (Take g = 10 m/s²)
