(chatquestion)...A uniform plate of mass m having equilateral triangular cross-section of side length 1 is placed at the edge of an obstacle inside a cart which is made to accelerate rightward with constant acceleration ao as shown, and obstacle can apply reaction in horizontal direction only. On the basis of above information, answer the following question (force F is applied horizontally at the apex of plates to keep it in equilibrium). Obstacle Question : If applied force F is large enough to just tilt the plate, then A ao F = m 3 Correct Answer (융 +음) ao F = 3 Vector sum of torque of weight and force F is zero (about obstacle) Vector sum of torque of weight and force F is non-zero (about obstacle) Correct Answer (Your Answer)...(Photo from Prem Sai)
