If F = 2.6 kN, determine the magnitude of the equivalent resultant force at A.  

Assuming that no unknowns have been solved for previously, determine how many unknowns will show up on the free body diagram of the properly aligned bar ABC if the supports at A, B and C are all journal bearings.  

The dot product results in a(n) ___________.  

Determine the tension in cable AC.  The tension in AD is 88 lb, the unit vector of AD is [18/55 i – 26/55 j + 45/55 k] and the unit vector of AC is [-24/51 i + 0 j + 45/51 k]. The weight of the crate is unknown.

Assuming the magnitude of force A is non-zero, it causes moments about which axes?  

Assume that the tension in the cable is known and creates force vector F applied to the pipe at B.  To put the force F in Cartesian vector form, you would use the following approach:  

Phosphorus trichloride reacts with chlorine gas in an equilibrium process to produce phosphorus pentachloride: PCl3(g) + Cl2(g) ⇌ PCl5(g)     ∆Hrxn = −88 kJ/molrxn The following particle-level diagram represents the contents of the vessel in an equilibrium mixture at 546 K If each particle in the diagram represents a partial pressure of 1.00 atm, what is the value of Kp for the equilibrium mixture at 546 K? Enter your numeric answer to 3 decimal places

Glycolate ion, C2H3O3− acts as a base in aqueous solution. When the glycolate ion reacts with water, it forms glycolic acid, HC2H3O3: C2H3O3−(aq) + H2O(l) ⇌ HC2H3O3(aq) + OH−(aq) At 25 °C, a 2.5 M solution of glycolate is found to have [OH−] = 1.3 × 10−5 M. What is the value of Kb for the glycolate ion?

Glycolate ion, C2H3O3− acts as a base in aqueous solution. A Lewis diagram for the ion is: Which labeled atom on the Lewis diagram will accept the proton when glycolate ion reacts with water?
