1. Calculate the acceleration of block A in ft/sec2 2. Calculate the acceleration of block C in ft/sec2 3. Calculate the tension in cord ABC in Ib.

A BB-series Astromech Droid of mass 154 kg is suspended by the truss structure shown. The truss structure is pinned to the wall at A and is supported by a rocker against the wall at F. A B 2w E F Allow w = 3 m. Determine the forces in all the members in the structure and indicate whether they are in tension or compression.

Using Tall = 68 MPa and G= 27 GPa, determine for each of the aluminum bars shown the largest torque T that can be applied and the corresponding angle of twist at end B. Refer to Table 3.1. (a) (b) 45 mm 15 mm 25 mm 25 mm 900 mm B Check my work B The largest torque that can be applied at end B of bar a is N-m and the corresponding angle of twist is The largest torque that can be applied at end B of bar bis N-m and the corresponding angle of twist is
