The 490-lb beam is supported at A and Bwhen it is subjected to a force of P= 1000 lb as shown. 8 ft -2 ft- Part A If the pin support at A suddenly fails, determine the beam's initial angular acceleration. For the calculation, assume that the beam is a slender rod so that its thickness can be neglected. Express your answer to three significant figures and include the appropriate units. You did not open hints for this part ANSWER: a = Part B Determine the force of the roller support on the beam. Express your answer to three significant figures and include the appropriate units.

1000 lb -8 ft +2ft A beam that weighs 300 lbs is supported by a roller and pin B and A respectively while being subjected to a force of 1000 lbs. If the pin at A is suddenly removed, determine the beams angular acceleration, the force exerted by support B and the horizontal acceleration just after A is removed. Assume the beam is a slender rod of negligible thickness. Please don't use angle measurements when solving. Use the 3-4-5 triangle to solve, if that makes sense. Thank you! Choutranco impgo tout

The motor lifts the 40-kg  crate with an acceleration of 6 m/s2 as shown in (Figure 1). Part A: Determine the x and y components of force reaction at the fixed support A using scalar notation. Express your answers in newtons to three significant figures separated by a comma.   Part B:  Determine the couple moment at the fixed support A. Express your answer in kilonewton meters to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.
