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
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)
A force of 10 N acts perpendicular to a wrench at a distance of 0.3 m from the pivot. What is the torque produced?
A ladder of length 5 m and mass 15 kg rests against a smooth wall making an angle of 60° with the ground. If the ground is rough, calculate the minimum coefficient of friction required to prevent slipping. (Take g = 9.8 m/s²)
A uniform beam of length 4 m and mass 20 kg is supported at its ends. A mass of 40 kg is placed 1 m from the left end. Calculate the reaction at the right support. (Take g = 10 m/s²)
A uniform disc of mass 2 kg and radius 0.5 m is supported horizontally at its edge. What is the torque due to its weight about the support? (Take g = 10 m/s²)
A uniform plank of length 6 m and weight 300 N rests horizontally on two supports placed 1 m from each end. What is the maximum distance from the left end that a 600 N person can walk before the plank tips?
A uniform rod of length 2 m and mass 10 kg is supported horizontally at one end. What is the force required at the other end to keep it horizontal? (Take g = 9.8 m/s²)
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.
Explain why a wider base increases the stability of an object.
State the conditions required for a body to be in static equilibrium.
