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 12
A 10 m long uniform beam weighing 500 N is supported at its ends. A 300 N weight is placed 2 m from the left end. Find the reaction at the left support.
A 2 m long uniform bar of mass 10 kg is supported at its ends. A 20 kg mass is suspended 0.5 m from the left end. Calculate the force at the right support. (Take g = 9.8 m/s²)
A 3 m long uniform rod of mass 6 kg is supported horizontally at its ends. A 12 kg mass is suspended 1 m from the left end. Calculate the force at the left support. (Take g = 9.8 m/s²)
A ladder of length 5 m and mass 20 kg rests against a smooth vertical 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 6 m and mass 12 kg is supported at its ends. A mass of 24 kg is suspended 2 m from the left end. Calculate the reaction force at the right support. (Take g = 9.8 m/s²)
A uniform beam of length 8 m and mass 40 kg is supported at its ends. A 60 kg mass is placed 3 m from the left end. Calculate the reaction at the left support. (Take g = 9.8 m/s²)
A uniform meter rule is balanced at the 40 cm mark when a 100 g mass is suspended at the 10 cm mark. Find the mass of the meter rule.
A uniform plank of length 4 m and weight 200 N rests horizontally on two supports placed 0.5 m from each end. What is the maximum distance from the left end that a 400 N person can walk before the plank tips?
A uniform rod of length 2 m and mass 8 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 'couple' in the context of statics.
Describe the difference between static and dynamic equilibrium.
Describe the principle of transmissibility of forces.
Explain why a body with a wide base and low center of gravity is more stable than one with a narrow base and high center of gravity.
Explain why a door is easier to open when you push at the edge farthest from the hinge.
State the conditions required for a body to be in static equilibrium.
