- A block of mass m = 1.34 kg (Block 1) at rest at Point A on an arc of smooth circular surface of radius L = 30 m. Another block of mass M = 3.22 kg (Block 2) is at the bottom of the arc as shown in Fig.6. The line between the center of the arc and Point A and the line between the center of the arc and Point B make an angle 0 = 35 deg. If Block 1 is released and slides on the arc and hits Block 2, Block 1 stops at Point B and Block 2 starts to move along the arc. What is the velocity of Block B right after the collision in m/s. Keep three significant figures for the answer. g= 9.80 m/s.

A guy wire is to be attached to the top of the tower and to the ground, 163 ft downhill from the base of the tower. The angle formed by the guy wire is 10°. Find the length of the cable required for the guy wire.arrow_forwardThe following forces are acting on the bracket below. The bracket has a width w of 2 inches and a height h of 3 inches. The bracket is in equilibrium (not accelerating). Determine F3y knowing F1x-98 lbf and F1y=195 lbf. For this question, what is F3.y in Ibf? Note that the y- direction is pointing up, so if the force is pushing down on the bracket, it has a negative magnitude. 39arrow_forwardA beam is supported by a roller at A and a pin at B.
