 P: 2 Two blocks each of mass m = 3.50 kg are fastened to the top of an elevator as in the figure below.--- this is a horizontal version cuz im on a comp. [top of elevator]--string1--[block #1 3.5kg]--string2--[block #2 3.5kg] (a) If the elevator accelerates upward at 1.6 m/s2, find the tensions T1 and T2 in the upper and lower strings. (b) If the strings can withstand a maximum tension of 87.0 N, what maximum acceleration can the elevator have before the first string breaks? m/s2 first time here, HELP!
 P: 328 You can start by drawing the free body diagram of the individual strings
 P: 2 I did, but I need some serious help aka answer. I have 2 free body diagrams. Can you give me the formulas to complete the question.. also using it as a template for other problems thanks

Well the only 'template' i can think of will be $$\sum F$$=ma where F is all the forces acting on a object. For your case T-mg=0 when they are in equilibrium aka not moving and T-mg=ma when they are moving and the 'a' will be the acceleration of the object.
