The uniform 217-kg bar AB is raised in the vertical plane by the application of a constant couple M = 4 kN·m applied to the link at C. The mass of the links is small and may be neglected. If the bar starts from rest at θ = 0, determine the magnitude of the force supported by the pin at A as the position θ = 51° is passed. Hint: This is a curvilinear translation problem.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
