Four forces (measured in Newtons) act on a crate. The forces are given by the vectors: F₁ = 2121-136j+241k N, F₂ = 108i + 144j+ 189k N. F₂ = -400i + 180j + 240k N, and F₁ = -270€ N a) What is the resultant, R = F₁+F₂ +F3 + F4, of the four forces? What is the magnitude of the resultant force? b) If the displacement of the crate is given by d = 0.5f-0.1j+2.7k m What is the contribution by the first force F₁ to the work done, i.e. W = F₁.d? c) If the third force, F3, acts at the point (0.5, 0.8,0.1) m, what is the moment, M = r X F3, at the point (-0.5,0.8,0.7) m?

In a tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the light, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left.
