- Compute the resultant of the concurrent forces shown in N. P1 = 265 N, P2= 303 N, P3 = 455 N, P4 = 192 N, 01 = 21, 02= 25, and 03= 10. Write numerical value only in 2 decimal places. P1 P4 03 8₂ + Y 0₁ P3 P2 + XCan someone answer this? ThanksWhy is the tension force in the vertical direction Tcos(theta) and not Tsin(theta). Isn't Tcos(theta) the force in the horizontal x diretion?
- A student is trying to determine the critical angle (0) at which block will slide down an incline. She knows the coefficient of static friction between the incline and the block is 0.53 and the coefficient of kinetic friction is 0.44. Neglect drag. Hint: One way to solve the problem is to solve for all quantities in terms of m, e and g (but not u), then use f= uN and a trig identity to solve for 0. What is the critical angle? 13 Would the the block slide if the incline angle were 35°? cannot be det check answers I Rain to stQ 5)A force vector F =3i + 3j N is applied on 5 kg mass of body on nonfrictionless horizontal surface.
