STATEMENT A gym decides to gradually replace its weight training equipment. Now, members who use type 1 equipment can also use type 2 equipment, represented in the figure, to lift loads corresponding to masses M₁ and M₂, at a constant speed. In order for the exercise to be performed with the same force F, users must be instructed regarding the relationship between the loads in the two types of equipment, since fixed pulleys only change the direction of the forces, while the movable pulley divides the forces. In both devices, consider the ropes inextensible, the masses of the pulleys and ropes negligible, and that there is no energy dissipation. For this gym, what should be the ratio M₂/M₁ informed to the users? A) 1/4 B) 1/2 C) 1 D) 2 E) 4 Answer ✅ Alternative D #enem #enem2023 #commentedquestions #physics #mechanics #dynamics #pulleys #simple_machines #force #traction #professorfilatte #entranceexams #medicine #tri
