B 60° Figure 3 L A 5. A beam AB of length 10m and negligible mass leans against a wall at an angle of 60° to the horizontal. It is held at B by a string as shown. There is no friction at either of the ends A or B. A koala of mass M = 10 kg climbs up the beam from B. If the breaking tension of the string is 40 N, find the distance reached by the koala just before the string cannot support any more weight and breaks.

an object weighing 65N is helf up on the air by two ropes. the first rope points uo to the right 30 degrees aboe horizontal and the other rope points up to the left at 45 degrees above horizontal. what is the tension in the two ropes?

The 6-m pole ABC is acted upon by a 460-N force, P, as shown in the figure. The pole is held by a ball-and-socket joint at A and by two cables BD and BE. For a = 3 m, determine the tension in each cable and the reaction at A. (Round the final answers to one decimal place.) 3. 1.5 m P E The tension in cable BD is The tension in cable BE is The reaction at A is - ( y C B 3 m N. N. N)i + 3 m 3 m 1.5 m 3 m X N)j + N)k.

Three people are pulling a heavy object along the floor with forces A, B and C as shown in the figure. What is the resultant (i.e. suml of the three forces? The forces are given by (all angles are CCW from + x-axis): A = magnitude 20 N, direction 30º. B = magnitude 40 N, direction 140°. C= magnitude 30 N, direction 240º. в А х-ахis

A circular disc bears against a frame structure and a wall, as shown inthe figure. All contacts with the disc are frictionless. The frame structurehas pin supports at A and B; there is an internal pin connection at C. If themaximum allowable reaction force at either of the pin supports is 8 kN, what isthe maximum allowable weight of the disk?

A box of mass 100.0kg rests on level ground and there is no friction between the box and theground. Resting on top of that mass is a 40.0kg mass with friction coecient that's unknown. A ropeis tied to the 100.0 kg mass and draped over a pulley from which a third mass hangs. How much massmust the hanging mass have in order for the acceleration of all masses to be 5ms2 ? What is the minimum possible friction coecient of the 40.0kg mass in the prior problem?
